Difference between DVD-R and DVD+R

Could someone please explain the difference in these two? I thought I read somewhere in this forum that the Superdrive in the flat panel iMac cannot do DVD+Rs. If this is so, why not?
I did a search but found no info. Thanks in advance for any help.

This article details the differences. I think it fair to summarize the DVD+R was never properly standardized by the DVD Forum but DVD+R offers better error protection as well as the ability to write Dual Layer disks. 
Apple intially stuck in the minus (DVD-R/RW) camp and moved to multi-drives later on. Here is Apple's article (much easier reading) - this article also explains how you check whether your iMac can read - or + disks.
Here's the full specs for the DVR-106 a 'Superdrive' fitted to many iMac G4 (Check in Apple System Profiler to see what model you have).
I realise I haven't fully answered your question but hopefully pointed you the right places to get your answers.

  • The difference between chapter markers and dvd studio pro markers

    Does anyone know what is the difference between chapter markers and dvd studio pro markers? I can not find anywhere on Google. Also in the tutorials I have seen, suggesting DVD Studio Pro markers, but it did not mention the chapter markers.
    Thanks,

    "Adding Chapter and Compression Markers to Your Sequence
    Once you have your edited sequence or program finished, you can add markers to the sequence for use on DVD. Markers are reference points you can place within clips or sequences that identify specific frames. There are two kinds of markers you can add that directly relate to authoring a DVD—chapter markers and compression markers.
    • Chapter markers allow DVD authoring applications to create a navigable chapter list for your exported QuickTime movie. Chapter markers force MPEG keyframes (known as I-frames) at their location, since the DVD specification requires an I-frame at each chapter point.
    • Compression markers identify areas of abrupt change and include two types: those that are automatically inserted by Final Cut Pro at all edit points, and those you manually place in the clip or sequence. Like chapter markers, compression markers force I-frames at their location, although in this case it is for better quality encoding, and they are not used to create a chapter list.
    Note: When you export a QuickTime movie, you have an option to export various kinds of markers, including compression, chapter, or DVD Studio Pro markers. *When you choose to export DVD Studio Pro markers, Final Cut Pro actually exports chapter markers and all compression markers.* This includes compression markers you set manually, as well as ones created automatically by Final Cut Pro at edit and transition points."

  • List of differences between PSE 40 and PSE30

    A lot of users are asking what are the differences between PSE 30 and PSE 40.
    This Thread provides information on this subject. First, you will find information copied from the section "New Features" of the useful "Adobe Photoshop Elements 4.0 User Guide". Then later on, you might find additional information on the same subject provided by users of PSE.
    --- Start of copy of information in the PSE 4.0 User Guide ----
    1 What's new in PSE 4.0
    1.1 Editing and selection
    1.1.1 Magic Selection Brush tool
    Easily and accurately select portions of your photos using this new tool in either Standard Edit and Quick Fix. Simply scribble or place dots on the object you want to select -no need to precisely outline the object- and Adobe Photoshop Elements selects the object for you. You can add to or subtract from the selection by using additional tools in the options bar. (See User Guide "To use the Magic Selection Brush tool" on page 193.)
    1.1.2 Magic Extractor.
    Easily select an object in a photo and extract it from its background. Just scribble or place dots on
    the object you want to extract; then scribble or place dots on the background, and Photoshop Elements separates the object from its background. This tool is perfect for creating composites or scrapbook images. (See User Guide "To use the Magic Extractor" on page 194.)
    1.1.3 Skin tone adjustment
    Click an area of skin and watch the tonal balance of all colors in the photo improve. If you
    want, you can also manually adjust the color by using color sliders. (See User Guide "To adjust the color of skin tone" on page 224.)
    1.1.4 Red eye removal

  • Differences between 2 pass and 1 pass compressing in compressor 2.0

    Is there a noticeable difference between 2 pass and 1 pass compression? It seems to me that sometimes 1 pass looks better than 2 passes. Strange...
    Thanks,

    Hey Girshon
    this is more of a compressor forum question, but i can answer it here
    theoritically, a 2 pass VBR encode is a MUCH better option if you are limited to space with VERY complex scenes. a cbr encode is optimal for short encodes, or encodes where you have NO space limitation. of course this is how most encoders work.
    in compressors case, for SOME reason (unbeknown to me) a 2 pass vbr does not encode to a quality that where i can call acceptable, especially with accepatable bit-rates.
    this problem has seemed to come in compressor v2. a lot of people that use this version of compressor seem to recommend a CBR in compressor or a 2 pass vbr IN DVD SP.
    compressor v1 seems not to have this problem however. as a matter of fact, a lot of other DVD encoder, software or hardware dont seem to have this problem.
    if you do a search for 2 pass vbr in the compressor forums, you will see all the quality problems associated with compressor 2.

  • Quality difference between S-video and RCA

    Can someone tell me what's the difference (in quality) between S-video out and RCA out?
    I'm using RCA out because with s-video, the image shows up in black and white on my TV.
    It would help to know I'm not loosing too much quality this way...
    Regards everyone.

    pauliewog is speechless  
    But what Robi says is true!
    The various forms of (analogue) signal transfer are, in descending order of quality:
    RGB - The Red, Green and Blue signals are generated by the PC (say), and connected by separate wires to ultimately control the Red, Green and Blue electron guns of the display monitor/TV set. The standard 15-pin "VGA" connector is RGB (plus H and V synchronising pulses).
    YUV - Also called Component, and YCrCb, as found on DVD players. The Y is the luminance, or Black-and-White component, while the Cr and Cb are the Differences between the Y and the Red and Blue signals respectively. Usually, the Y signal has higher bandwidth than the Cr and Cb signals (twice as many Y samples as Cr and Cb samples on the DVD). Still needs wires, but the Sync is added to the Y signal.
    Y/C - aka S-Video. The Y is as above, but the Cr and Cb signals are used to modulate a subcarrier (3.579545MHz for NTSC, 4.43361875MHz for PAL), with one of the signals effectively at 90 degrees to the other - the C signal. The bandwidths of the colour difference signals need to be bandwidth limited to about 1/3 of the subcarrier frequency (about 1.7MHz for PAL from memory), compared to the Y bandwidth of 5MHz for broadcast television. In PAL, the phase of one of the signals is inverted every other line (PAL = Phase Alternating Line, aka Peace At Last). Transmission errors which result in green faces and purple trees in NTSC (National Television Standards Commitee, aka Never Twice the Same Colour) tend to desaturate the colours instead.
    CVBS, aka Composite Video (also RCA, named after the company that developed the type of connector used, which is typically yellow for video). The Y and C (and sync) signals are combined one one wire. The TV has a harder job of separating them back to RGB  :(
    RF (Radio Frequency). The CVBS signal is modulated onto an RF carrier, which could be anywhere between about 45MHz and about 1000MHz (not counting satellite distribution), so that it looks the same as a broadcast TV station to a TV set, and connects via a single cable to the antenna socket of a TV set. So first the TV has to demodulate the signal back to CVBS, before separating the Y and C, then separating the C into Cr and Cb and putting into a matrix with the Y to get RGB back. Nevertheless, this is a useful technique for distributing a signal to a lot of TV sets over a reasonably large area. It is also the only method that works with old TVs without A/V inputs - which is why game consoles used to come with an RF Modulator (aka RF Converter) as standard.
    The above methods are also in descending order of signal bandwidth, which restricts the available resolution, or the finest horizontal detail (especially colour detail). Generally, 800x600 is about as good a resolution as you can expect to get on a TV display without resorting to special enhancing techniques.
    The above is probably a lot more detail than you need, but is still a fairly superficial explanation. But study it up, the test is next Monday at 9am  :D

  • What is difference between sy-tabix and sy-index.

    SAP Seniors,
    Can you please let me know what is difference between sy-index and sy-tabix.
    I read the SAP help, it is confusing for me. it looks like both are same from help. please help me.
    Thank you
    Anitha.

    HI,
        Here is a brief description of difference between SY_TABIX and SY_INDEX and using them with several conditions.
    SY-TABIX
    Current line of an internal table. SY-TABIX is set by the statements below, but only for index tables. The field is either not set or is set to 0 for hashed tables.
    APPEND sets SY-TABIX to the index of the last line of the table, that is, it contains the overall number of entries in the table.
    COLLECT sets SY-TABIX to the index of the existing or inserted line in the table. If the table has the type HASHED TABLE, SY-TABIX is set to 0.
    LOOP AT sets SY-TABIX to the index of the current line at the beginning of each loop lass. At the end of the loop, SY-TABIX is reset to the value that it had before entering the loop. It is set to 0 if the table has the type HASHED TABLE.
    READ TABLE sets SY-TABIX to the index of the table line read. If you use a binary search, and the system does not find a line, SY-TABIX contains the total number of lines, or one more than the total number of lines. SY-INDEX is undefined if a linear search fails to return an entry.
    SEARCH <itab> FOR sets SY-TABIX to the index of the table line in which the search string is found.
    SY-INDEX
    In a DO or WHILE loop, SY-INDEX contains the number of loop passes including the current pass.
    Hope this helps.
    Thank you,
    Pavan.

  • What is difference between sy-index and sy-tabix and where both are using ?

    what is difference between sy-index and sy-tabix and where both are using ?

    hi nagaraju
    sy-tabix is in Internal table, current line index. So it can only be used while looping at the internal table.
    sy-index is in Loops, number of current pass. This you can use in other loop statements also (like do-enddo loop, while-endwhile)
    SY-INDEX is a counter for following loops: do...enddo, while..endwhile
    SY-TABIX is a counter for LOOP...ENDLOOP, READ TABLE...
    Here is an example from which you can understand the difference between sy-tabix and sy-index.
    Itab is an internal table with the following data in it.
    id Name
    198 XYZ
    475 ABC
    545 PQR.
    loop at itab where id > 300.
    write :/ itab-id, itab-name , sy-tabix, sy-index.
    endloop.
    My output will be :
    475 ABC 2 1
    545 PQR 3 2
    Sy-tabix is the index of the record in internal table.
    sy-index gives the no of times of loop passes.
    So, for the first record in the output (475 ABC), 2 is the index of the record in internal table and as it is first time loop pass occured, sy-index value is 1.

  • The difference between an iphone and an ipod touch?

    i want to know if the difference between an iphone and an ipod touch is just that the iphone is like a phone that has internet and is a phone. or what else is it?

    The iPhone includes the same as an iPod Touch but also includes a phone, a camera, and a GPS radio.
    In addition to having internet access via wi-fi, the iPhone also has internet access via the cellular network, so as long as you have cellular reception with the iPhone, you have access to the internet in addition to having access via an available wi-fi network.

  • The difference between system restore and last good known configuration

    hi,
    what is the difference between system restore  and last good known configuration.
    in which situation you use system restore ,and in which situation you use last good known configuration.
    very short answer wil be enough.
    thanks
    johan
    h.david

    Last Known Good Configuration deals only with Starting Windows eg. a bad registry or incorrect driver is preventing Windows to start.It recovers the registry settings of HKEY_LOCAL_MACHINE\System\CurrentControlSet
    While System Restore uses restore points to return your system files and settings to an earlier point in time without affecting personal files. Restore points are created automatically every week, and just before significant system events, such as the installation
    of a program or device driver. You can also create a restore point manually.You can undone system restore but there is no such option in Last Known Good Configuration.
    Last Known Good Configuration is disabled in Windows 8 or,Windows 8.1 by default.
    Try using Last Known Good Configuration if you can't start Windows, but it started correctly the last time you turned on the computer.
    Try using System Restore to return the system to an earlier point in time when things worked correctly.

  • What is the difference between Topic Keywords and Index File Keywords?

    What is the difference between Topic Keywords and Index File Keywords? Any advantages to using one over the other? Do they appear differently in the generated index?
    RH9.0.2.271
    I'm using Webhelp

    Hi there
    When you create a RoboHelp project you end up with many different ancillary files that are used to store different bits of information. Many of these files bear the name you assigned to the project at the time you created it. The index file has the project name and it ends with a .HHK file extension. (HHK meaning HTML Help Keywords)
    Generally, unless you change RoboHelp's settings, you add keywords to this file and associate topics to the keywords via the Index pod. At the time you compile a CHM or generate other types of output, the file is consulted and the index is built.
    As I said earlier, the default is to add keywords to the Index file until you configure RoboHelp to add the keywords to the topics themselves. Once you change this, any keyword added will become a META tag in the topic code. If your keyword is BOFFO, the META tag would look like this:
    <meta name="MS-HKWD" content="BOFFO" />
    When the help is compiled or generated, the Index (.HHK) file is consulted as normal, but any topics containing keywords added in this manner are also added to the Index you end up with. From the appearance perspective, the end user woudn't know the difference or be able to tell. Heck, if all you ever did was interact with the Index pod, you, as an author wouldn't know either. Well, other than the fact that the icons appear differently.
    Operationally, keywords added to the topics themselves may hold an advantage in that if you were to import these topics into other projects, the Index keywords would already be present.
    Hopefully this helps... Rick

  • Whats is difference between Java JRE  and  Java SDK

    Hi,
    what is the difference between Java JRE and Java SDK...
    i think both of them have the same set of files to be installed...
    I am not able to understand where they differ

    The JRE (Java runtime Environment) contains just the stuff necessary to run Java and the SDK (System Development Kit) contains the extra stuff necessary (and also helpful) to develop in Java.

  • Disk Utilty - what is difference between single volume and single partition

    In Disk Utility I can, should I wish, format a drive by using Erase to create a single volume. Also in Disk Utility, I have the option to use Partition to create one (or more) partition.
    What is the difference between a volume and a single partition?
    What are their relative merits?
    In what circumstances would I want to create a single partition instead of a volume?
    Disk Utility also prompts me to name the volume or partition. From experience, what would you suggest as a suitable name and where is this information subsequently used?

    A "volume" or "partition" are the same thing. The subject of using partitions has been covered many times on the forums. Do some searching and you'll find quite a lot of information. Also try doing some Google searching.
