Odd problems with reading DVD media [concluded]

There is an odd problem I've encountered...(I'm not sure if its a bug with Arch Linux or Linux in general).
Firstly, the details:
* I've updated the systems (using "extra", "current", and "community" respositories). So its the current one (0.80 "Voodoo"). I'm NOT using "Unstable" respository.
* I've already added the user to the "optical" and "storage" groups. So there's no problems in relations to permissions.
* My fstab entries for the CD and DVD drives are default (I didn't touch them)...That is, "iso9660" and "udf" respectively.
* My desktop environment is KDE 3.5.5...And I have changed the behaviour of the desktop icons such that DVD media, CD media, and USB devices will have an icon pop-up as soon as you plug them in.
* I have "hal" loaded in the DAEMONS of /etc/rc.conf
* I'm using 4 different Linux systems with the following DVD burners.
=> Pioneer DVR-108
=> Sony DW-Q120A
=> Hitachi-LG GCC-4240N (DVD-ROM/CD-burner combo)
* There are three Sempron 2800+ (Socket 754, 1.6Ghz) boxes and the last one is on an IBM R40 ThinkPad, and I know you can't read DVD-R media on that. But it should be able to read DVD+R media without issue.
* Two of the Semprons are running Arch, as well as the ThinkPad. The final Sempron box is running Ubuntu 6.06.1
* When I installed K3b I did: pacman -S k3b dvd+rw-tools
* All the DVD media is Verbatim DataLifePlus ones.
Here's what I've done...
I've burnt two DVD media (they're just video files from last year's Blender 2006 conference thing, so its legal stuff).
One is a DVD+R and the other is DVD-R media. Both were done on a Windows 2000 Pro SP4 box using Nero 6.6.1.4
What's the problem?
Well, KDE in the Arch Linux boxes doesn't recognise the media!...There is no DVD icon that automatically pops up on any of the Arch Linux boxes!
When I run dmesg on the Arch boxes, the only relevant info I get is:
ISO 9660 Extensions: Microsoft Joliet Level 3
ISOFS: changing to secondary root
Now if I re-insert these DVD media onto an Ubuntu 6.06.1 LTS box...The DVD+R works perfectly! While the DVD-R does not.
When I run dmesg on this box, I get the following:
[17179654.808000] hdc: cdrom_decode_status: status=0x51 { DriveReady SeekComplet e Error }

If I re-burn the data onto a DVD+RW, Arch and Ubuntu immediately sees it, and KDE (or Gnome in Ubuntu), will have a DVD icon popping up! I can view the video clips without issue!
Now here's the really odd part...
When I load up K3b on either Arch OR Ubuntu, they recognise all DVD media! (As in, they can read the media disc information!)...Tools => DiskInfo
If I click on the PIONEER - DVD-RW DVR-108 on the tree menu on the left side in K3b, (to view the contents of the DVD-R or DVD+R media), it can't read and pops up an error message informing about a read problem. It suggests I try dmesg|tail to see what's wrong.
When I do that, I get...
# dmesg|tail
grow_buffers: requested out-of-range block 18446744073708569376 for device hdc

grow_buffers: requested out-of-range block 18446744073708569376 for device hdc
UDF-fs: No partition found (1)
I repeat the same procedure on DVD+RW, and it works perfectly!
Should I use another burning application instead of Nero on the Windows box?
Could it be the way I burn things?
(Some DVD+R and DVD-R are burnt with multisession while others aren't.)
Has anyone else experienced similar issues?
What are your "workarounds" or fixes?

It *should* work...But they don't.
I tried this...
mount -t auto /dev/dvd /mnt/dvd
I get this...
mount: block device /dev/dvd is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/dvd,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
I then do dmesg|tail
grow_buffers: requested out-of-range block 18446744073708569376 for device hdc
UDF-fs: No partition found (1)
If I try this...
mount -t iso9660 /dev/dvd /mnt/dvd
I get this...
mount: block device /dev/dvd is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/dvd,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
I then do dmesg|tail
Unable to identify CD-ROM format.
If I stick in a DVD-R that is burnt in one go without multisession, I get this in the dmesg
UDF-fs: Partition marked readonly; forcing readonly mount
UDF-fs INFO UDF 0.9.8.1 (2004/29/09) Mounting volume 'SW', timestamp 2006/11/07 19:37 (1000)
It reads this disc perfectly and KDE pops up a DVD icon.
I'm scratching my head as I'm not sure what is the problem.
Could it be hal or the way the DVD media was formatted?

MOVED: Problem with SATA DVD/RW

This topic has been moved to AMD64 nVidia Based board.
Problem with SATA DVD/RW

I use the Plextor PX-712SA's with no issues. However...I do not believe the SATA versions require jumpers. Try plugging them in on SATA port 1 or 2, making sure those are enabled in BIOS of course. Make sure all connections are secure. There have been some issues with these particular drives not operating properly, but it has not been an issue with seasoned system builders, so the problems may be with the builder himself. Usually, Plextors are so good, they'll almost burn a paper plate! Try a different medium, maybe another brand of blank CD or DVD.
You may also want to check Device Manager in Windows, to see if it is listed "This device is working properly"!

Im having problem with the dvd quality, I'm using compressor to convert the video fils from apple prores to mpeg2 .It doesn't matter how long my video is even if its just 5 minutes I'm getting cut edges in the video , does anyone have any idea ?

Im having a problem with the dvd quality, I'm using compressor to convert the video fils from apple prores to mpeg2 .It doesn't matter how long my video is even if its just 5 minutes I'm getting cut edges/lines in the video specialy if i have titles it comes up really bad , I took the same video to a friend of mine who have PC and he uses Encore , did the encoding there and it was just fine no problems! BTW I tried using doferent setings in compressor from CBR and VBR I even pushed up the setings to 8 or 9 BR and still no luck !
does anyone have any idea ?
Thanks in advence ...

Let's focus attention on just the Sony. (What model and what resolution are you shooting?)
For now, I'll assume you're shooting 1080i.
Take a representaive clip into a new sequence. Add a title.
In your sequence, make sure field dominance is set to Upper.
Set render settings to Pro Res 422.
After rendering, export QT self contained.
Import into Compressor (I'm now referring to v3.5).
Select the 90 minute Best quality DVD preset.
Open frame controls and turn on (click the gear icon). Set Resize filter to Best.
Submit burn and check quality on TV.
Good luck.

Problem with copied DVDs--"DAMAGED TS FOLDER" (HELP or I shall go MAD!)

Hi folks--really, really hope someone can help me. This has got me beat. And I'm by no means sure it's a problem with my computer, but...
The facts:
1. I recently acquired a Panasonic DMR-ES20 DVD recorder, primarily to make DVD copies of a number of old and treasured videotapes. These are from broadcast, so copy protection isn't a factor.
2. I often use my Mac as a TV to watch DVDs and have never had the slightest problem with commercial DVDs.
3. I am (or was) using Roxio's Popcorn 2 program to make up backup copies of the DVDs I make.
4. I made about 20 DVDs without problem, and ALL work perfectly on the Imac, and ALL can be copied via Popcorn 2.
5. Then, SOMETHING CHANGED, I have no idea what--but now, each and every DVD I make with the Panasonic shows up on the Imac as follows:
"The TS folder appears to be damaged."
These disks will NOT play on the Imac and cannot be copied with Popcorn 2. They DO play on the Panasonic machine, however.
6. I have tried varying media, including high-quality Taiyo Yuden disks. That didn't help.
7. I have reset the recorder to original factory settings. That didn't help.
8. I have used a disk lens cleaner on the Imac. That didn't help.
9. I have spoken with Applecare and (God help me) Panasonic. Both pronounced themselves baffled.
10. As am I. As things stand, I've got a lot of more or less useless equipment. Ideas? Hints? Suggestions?

The only time I have ever expierianced an issue like this is from doing extensive burning. The cause is from the storage of the cache files and some of the older TS folders even after you trashed them from your machine after you burned.
The only way I have been able to work around this is
First Repair Permissions as is submitted by Gulliver.
http://discussions.apple.com/thread.jspa?messageID=607640&#607640
I have also found that by running 3 freeware or shareware programs one right after the other and after the 3rd it will restart your computer all is well when I do it.
First run Macjanitor.
http://personalpages.tds.net/~brian_hill/downloads.html
Next run Cache Out X.

And last but not least is ONYX.
take note when you run Cache out X and Onyx be careful to not delete your favorites in your browsers.

A note of interest, I have had to do this after I have done a lot of copying to get rid of all the excesive junk that is left behind.
Give it a try.
Good Luck Don

Problems with burned DVD in iDVD - Works in some players, not in others

Hi, I'm having a strange problem with a DVD I burned in iDVD.
I have a disc image that I made in iDVD and then burn the Audio_TS and Video_TS folders to a DVD.
I burned to a Memorex DVD+R.
The video pops up fine and plays on my computer after it burns, but if I eject the disc and try to re-insert it, the DVD preview says "Supported disc not found". It did this same thing when I tried it in my Macbook.
It works fine in my standard DVD player, but I also tried it on my Playstation 3 and it did not play.
A few things I am going to try is buring directly from iDVD instead of first making a disc image, and also using DVD-R, although I heard that DVD+R is generally a better format to use.
Someone also told me that DVD+R does not play on macs, which I question.
If anyone has any other suggestions or might know why this is happening, I would greatly appreciate it. It is an important project that needs to be done soon! Thanks.

The disc image option is within iDVD: File > Save as Disc Image. If you switch to DVD map map mode you can drag your movie to a spot prior to the menu so that the movie plays automatically when put into the player. Under advanced, you can set the movie to loop.... otherwise I think it goes back to the menu when done playing. BTW, all DVDs MUST have a menu it is part of the DVD specification. It is just a matter of whether you see the menu. As far as exporting your project back to tape... you won't loose any quality and your audio, along with your video and any editing to each will export back to tape. However, a MP3 is not generally considered a higher quality file (although perhaps the recorder was closer to the source?). As a matter of fact, if you are editing your audio I strongly suggest using a file sampled at at least 16-bit/48Khz, AIFF (or WAV or anything lossless).
In regards to the slow burn speed: I agree that a slower burn speed is better than the fastest burn speed (due to error corrections ect). However, I would choose a middle of the road burn speed. If my choices are 4x, 6x, or 8x, I would choose 6x. If it is 2x, 4x, 6x, I would choose 4x. And yes, quality of blank media can effect the playback of a disc that played once just fine.

Problem with burning DVD's

I have Roxio Toast Titanium and I have a problem with burning DVD's. When I put a blank DVD-R in my superdrive, select the files and go to burn; the advanced recording options will not let me deselect the check in "close disk". It is shaded. But when I use a CD-RW I can and so far the Roxio help has...well has not been help at all. I mean why would I spend the money to buy a software package that lets me do the same thing as the basic OS-X disk utility would let me do? Drag a file, burn it and close the disk from any future use....
Sorry if this does not belong here, I did not see a area for general software questions way back in the main forum area not one here.
Rob

Donald,
Hi and thank you.
To give you more details on what I am trying to do; I am trying to burn in Mac & PC format. I am mainly trying to back up all my assorted college files (I am a college student), these files are lecture notes in Word with embedded audio recordings, standard Word documents such as essays, etc., spreadsheets, PDF documents, etc. The files I am attempting to burn should not be larger than 4.7 gb and Roxio has not given me a warning that it would be.
I am just frustrated that when I put in a DVD-R or -RW I only have one option, and that is to close out the disk when it is finished burning it. I have also gone to the recording tab, on the menue bar, to uncheck the "close disk" box after I put in a blank DVD and before I select files to burn. The option is shadded preventing me from even trying, which is not the case for a CD!
Thank you!

Problems with my DVD/CD-ROM Drive (MS-8216)

I have a BIGGGG problem with my DVD/CD-ROM Drive (MS-8216)
I was copying somethin in my comp, and the cd got BOOOM into pieces inside.
My warranty expired 1 month ago, so i clean it in the inside. After this it is like this :
- i can watch 700mb movies AVI format with no problems, but when i want to copy anything in my comp from the cd it always stops rotating at 6% of copiyng and BANG it stops and an error has acourde. Same with the dvd's. Please don't ask me about my comp config couse i know it has no problem with that. I left every thing like it was inside --- impecable, no wiress unplugged and i've upgraded the firmware also
What can it be. Thank you

if you can read the CD, but not copy from it, try this program:
Isobuster
It allows you to read with a much better accuracy than the generic windows driver.
However, i'm afraid your drive has been damaged in the explosion and this is only a work around, not a real solution.
The good point is that DVD burner are now cheap, but it is not much...

Problem with READ Statement in the field routine of the Transformation

Hi,
I have problem with read statement with binary search in the field routine of the transformation.
read statement is working well when i was checked in the debugging mode, it's not working properly for the bulk load in the background. below are the steps i have implemented in my requirement.
1. I selected the record from the lookuo DSO into one internal table for all entried in source_packeage.
2.i have read same internal table in the field routine for each source_package entry and i am setting the flag for that field .
Code in the start routine
select source accno end_dt acctp from zcam_o11
into table it_zcam
for all entries in source_package
where source = source_package-source
     and accno = source_package-accno.
if sy-subrc = 0.
delete it_zcam where acctp <> 3.
delete it_zcam where end_dt initial.
sort it_zcam by surce accno.
endif.
field routine code:
read table it_zcam with key source = source_package-source
                                             accno = source_package-accno
                                             binary search
                                             transportin no fields.
if sy-subrc = 0.
RESULT = 'Y'.
else.
RESULT = 'N'.
endif.
this piece of code exist in the other model there its working fine.when comes to my code it's not working properly, but when i debug the transformation it's working fine for those accno.
the problem is when i do full load the code is not working properly and populating the wrong value in the RESULT field.
this field i am using in the report filter.
please let me know if anybody has the soluton or reason for this strage behaviour.
thanks,
Rahim.

i suppose the below is not the actual code. active table of dso would be /bic/azcam_o1100...
1. is the key of zcam_o11 source and accno ?
2. you need to get the sortout of if endif (see code below)
select source accno end_dt acctp from zcam_o11
into table it_zcam
for all entries in source_package
where source = source_package-source
and accno = source_package-accno.
if sy-subrc = 0.
delete it_zcam where acctp 3.
delete it_zcam where end_dt initial.
endif.
sort it_zcam by surce accno.
field routine code:
read table it_zcam with key source = source_package-source
accno = source_package-accno
binary search
transportin no fields.
if sy-subrc = 0.
RESULT = 'Y'.
else.
RESULT = 'N'.
endif.

I am facing a Problem with reading images from database

Hi everybody..
any help will be most appreciated, I am facing problem with reading images from database. I am pasting my code...
string connect = "datasource = localhost; port = 3306; username = root; password = ;";
MySqlConnection conn = new MySqlConnection(connect); // creating connecting string
MySqlCommand sda = new MySqlCommand(@"select * from management.add_products ", conn); //creating query
MySqlDataReader reader;
try
conn.Open(); // Opening Connection
reader = sda.ExecuteReader(); // Executing my Query..
while (reader.Read())
byte[] imgg = (byte[])(reader["Picture"]);
if (imgg == null)
pc1.Image = null;
else
MemoryStream mstream = new MemoryStream(imgg);
pc1.Image = System.Drawing.Image.FromStream(mstream);
It says Parameter not Valid... i am reading all the images from database

I agree with Viorel. You are getting the error because the format of the data is incorrect probably because the data was modify. It may not be the reading of the database the is incorrect, but the application that wrote the data into the database. You need
to compare the imgg array data with the data before it was written to the database to see if the data matches. I usually start by comparing the number of bytes which is easier to check then compare the actual to isolate which function is changing the
byte count.
An image is binary data. The standard VS methods for reading and writing data (usually stream classes) default to ASCII encoding which will corrupt binary data. The solution usually is to use UTF8 encoding instead of the default ascii encoding.
Ascii encoding with stream often aligns the data and adds extra null bytes to the end of the data which can produce these type errors.

Problem with reading config file

Hello,
I have problem with reading config file from the same dir as class is. Situation is:
I have servlet which working with DB, and in confing file (config.pirms) are all info about connection (drivers, users, passw, etc.). Everything work fine if I hardcoded like:
configFileName = "C:\\config.pirms";I need to avoid such hardcoding, I tryied to use:
configFileName = Pirms.class.getClassLoader().getResourceAsStream ("/prj/config.pirms").toString();but it isn't work.
My config file is in the same directory as Pirms.class (C:\apache-tomcat-5.5.17\webapps\ROOT\WEB-INF\classes\prj)
Also I tryied BundledResources, it isn't work fo me also.
Can anybody help me to solve this problem? with any examples or other stuff?
Thanks in advance.
Andrew

Thanks, but I am getting error that "non-static method getServletConfig() cannot be referenced from a static context"
Maybe is it possibility to use <init-param> into web.xml file like:
<init-param>
<param-name>configFile</param-name>
<param-value>/prj/config.pirms</param-value>
</init-param>If yes can anybody explain how to do that?
I need to have that file for:
FileReader readFile = new FileReader(configFile);Thanks in advance.

Satelite 1400-503 problem with a DVD+R

Hello,
I have a problem with my dvd - rom. Family of me have burned a dvd+R. Now can't i play it on my notebook. So i tested a dvd-R and this works well.
A friend of me tells me that i can change some configuration of something like that so i can play the both formats. Can someone help me with this???

Hi
I don't think this is a setting to be changed. The drive must support the + format.
This is not very common if the machine is not very very new. If You get this problem with the built-in drive of Your Sat1400-503 and it is not replaced by some unsupported one, then I am very sure that it does not support the DVD+R format.

Problem with reading mp4 files with QT 7.4.1 or mpeg Streamclip

Hi,
I used to convert some .flv files into .mp4 files with iSquint and then into .dv files with mpeg Streamclip in order to re-work and compile these files on a DVD using iMovie and iDVD.
However I cannot do it anymore since I upgraded to QT 7.4.1. iSquint uses the mpeg-4 video codec to convert the file. Therefore I cannot open them with QT 7.4.1 anymore and I cannot convert them into .dv files with mpeg Streamclip anymore since Streamclip is uses a QT plug-in.
I have tried to solve the problem using Perian but this plug-in does not work with my version of Mac (Panther 10.3.9). I also tried to downgrade to an older QT using Pacifist but it nearly crashed my whole computer (fortunately I could fix that by reinstalling QT 7.4.1).
Has someone a solution to my problem?
Thank you in advance.
Steve

Not all the following will apply to Panther (10.3.x) so look carefully on the sites mentioned for the correct versions:
These are the downloads and the settings you need in order to view/hear pretty much everything that the net can throw at you: The setup described below has proved repeatedly successful on both PPC and Intel macs, but nothing in life carries a guarantee!
It is known to work in the great majority of cases with Safari 3.0.4, QT 7.3 or 7.4 and OS 10.4.11. (If you are running Leopard, ensure that all plug-ins have been updated for OS 10.5)
Assuming you already run Tiger versions OS 10.4.9 or above (this has not yet been verified with Leopard) and have Quicktime 7.2 or above, and are using Safari 2 or 3, download and install (or re-install even if you already had them) the latest versions, suitable for your flavor of Mac, of:
RealPlayer 10 for Mac from http://forms.real.com/real/player/blackjack.html?platform2=Mac%20OS%20X&product= RealPlayer%2010&proc=g3&lang=&show_list=0&src=macjack
Flip4Mac WMV Player from http://www.microsoft.com/windows/windowsmedia/player/wmcomponents.mspx (Windows Media Player for the Mac is no longer supported, even by Microsoft)
Perian from http://perian.org/
You should read this support page http://perian.org/#support in case you need to delete older codecs.
Adobe FlashPlayer should first be uninstalled using the appropriate uninstaller available here: http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14157&sliceId=2 and then the latest version obtained from here: http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash and installed.
(You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS.)
In earlier versions than QT 7.1.3 in Quicktime Preferences, under advanced, UNcheck Enable Flash, and under Mime settings/Miscellananeous only check Quicktime HTML (QHTM).
You should also ensure, if you are running Tiger 10.4.11 or Leopard, that you have downloaded and installed the correct version for your Mac of Security Update 2007-009.1.1, which also deals with the Quicktime/Flash issues you may have experienced, such as the '?'. What happened was that both Quicktime as well as Adobe FlashPlayer tried to play the Flash video at the same time. This no longer happens. (N.B. Security Update 2007-009 1.1 requires both a restart and a permission repair.)
If you get problems with viewing video on a website try moving this file to your Desktop:
Hard drive/Library/Internet Plug-Ins/QuickTime Plugin.webplugin
and then restarting Safari. If all now works, you can trash that file.
In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them). However it should be noted that Perian is not an internet plugin and will not play DivX files imbedded on a website. For that you will need the DivX Player browser plugin available from http://www.divx.com/divx/mac/
Now go to Safari Preferences/Security, and tick the boxes under Web Content (all 4 of them) to enable Java.
Lastly open Audio Midi Setup (which you will find in the Utilities Folder of your Applications Folder) and click on Audio Devices. Make sure that both Audio Input and Audio Output, under Format, are set to 44100 Hz, and that you have selected 'Built in Audio'.
Important: Now repair permissions and restart.
You should also consider having the free VLC Player from http://www.videolan.org/ in your armory, as this plays almost anything that DVD Player might not.

Problem to read DVD+R DL

Since I can remember, I never read a DVD+R DL in my MacBook Pro 15'' 2009. I have a MATSHITA DVD-R UJ-868.
What could be the problem?
Thanks very much!

I have a problem when trying to read a burned DVD-R
DL. The system just ejects the DVD after about 20-25
seconds of trying to read it. The same thing happens
when I put in a blank DL DVD. The format is DVD-R
DL, which I believe this iMac should be able to
read/write.
Any advice? - Thanks.

If you look your profile tells you that Matshita works with +R DLs.
