40TL938G: no sound playing MKV files

Hello,
Last week I have purchased a Toshiba TV, type 40TL938G and I have two major problems which bother me very much.
Today, I spoke to the Toshiba Call Center from Romania.
I'd like to tell me if the future this problems can be solve or I'll be forced to sell it, because this TV does not satisfy my expectations.
So, the first problem is that if I want to browse of the net on some movies sites and I can't really see them, which is very, very annoying for me.
The guys from Toshiba Call Center told me that it's because the browser don't support viewing of any movie but does not seem normal as long as Samsung, LG and Sony have resolved these problems and specialists from Toshiba don't till now.
This is a very bad advertisement for Toshiba TVs and if my friends and my clients ask me if I'm satisfied with the Toshiba products, I can say only that I'm not satisfied, really.
The second problem that bother me a lot and I'm unhappy again is that on package and features TV is written that this TV supports MKV files but nowhere and no one wrote that Toshiba TV support MKV files but no sound because the sound does not working.
I tried to do a firmware update for this model but no exist.
It's possible soon to solve these two problems? If these problems hasn't solutions I'll be forced to sell it and to make a bad advertising for Toshiba's products, because I'm IT dealer and I have many clients and I don't want to lie my clients about product defects.
I'm waiting for an answer from you, soon as possible.
Thank you.
Best regards,
Robert

The MKV files are supported. But the mkv files have to support the right audio codec!
Found the info in the user manual (page 90)
http://www.toshiba-om.net/LCD/PDF/English/TL938-4046-English.pdf
_MKV files_
*Video codec:* MPEG-1 Video, MPEG-2 Video, MPEG-4 part2, H.264 (MPEG-4 AVC)
*Audio codec:* MPEG-1/2 Layer2, MPEG-1/2 Layer3, Dolby Digital (AC-3), L-PCM, MPEG-2/4 LC-AAC, MPEG-4 HE-AAC
>The guys from Toshiba Call Center told me that it's because the browser don't support viewing of any movie
Sorry mate that you are missing some features but fact is that this is a TV browser and it may work differently than PC browsers. The manual says that this browser does not support platform-dependent technologies such as Active X and it supports only preinstalled plug-ins.
If flash plugin isnt preinstalled you will not be able to watch flash based content.
By the way: it occurs to me that you are thinking to speak to Toshiba stuffsorry mate, this is user to user forum and we all here are enthusiasts

Playing .mkv files in QTX/QT7 video works fine, sound is distorted.

What I'm trying to do is open some .mkv files in Quicktime 7 so that I can export it as an mp4 with AAC audio (instead of AC3, 5.1). The audio during playback ends up sounding like a helicopter or what you'd hear if you stuck a piece of sandpaper in a box fan. When I play the files in VLC the audio is as it should be. I'm at a loss as to what the problem could be. I have version 1.2.1 of Perian installed as well if that helps at all.

It could be a 'difficult' form of Matroska file. FYI Matroska is just a container like MOV or AVI, and some mkv have the video encoded with Real Video Codec (RV9 RV10). Perian+QT can't decode this, but VLC will play .mkv files just fine on OS X, as long as they don't use H.264!
It's a bit of a lottery until Matroska decide to support the Apple platform. I have found this:
http://mkv4mac.free.fr/index.php?lang=en&p=lec
which may help.
But there may be another workaround: 1. Get Info the mkv file
2. Change to extension to wmv. Save as wmv and that could work better.
Or this link may be helpful:
http://www.squidoo.com/mkv-converter-mac
Recently, a poster (ZachP14) suggested this:
"There's a program called Plex that runs .mkv files awesome on my 2.0 ghz macbook."
http://www.plexapp.com/
Maybe worth a try?

Can apple TV be made to play .mkv files?

Has anyone been able to make apple TV play .mkv files?

If you install http://perian.org/ quicktime will be able to play mkv files including the ac3 audio.
You can use Quicktime to save the file as a mov which should then play on the AppleTV. Personally I use VisualHub, it's much faster and allows you to queue up a batch to process. It will depend on your system, but my machine will recode a TV show in approx. 30mins.
The Visualhub method will loose the surround sound. AC3 and DTS are not supported by the mp4 container so it will be converted to stereo. You should be able to keep the AC3 or DTS in a mov, but I've not tried this so I don't know whether the AppleTV will play the file.
As the new firmware will allow for HD movies with surround sound (according to the MacWorld keynote) there might be a fix for this then. We'll have to wait for someone to rent a movie and see what the container and codecs used are. Hopefully we'll be able to use 5.1 AAC and the AppleTV will convert that to AC3 out of the optical output for my surround amp as AC3 and DTS take up a lot of space.

Unable to play .mkv files

I used to be able to play .mkv files with VLC Player just fine before. After I started using Boot Camp with Windows XP, I am unable to play such files because I get an error message saying this computer is too slow to process the video. I'm trying to play 720p movies, but haven't been able to on a 2.2 Ghz MBP with 2 Gigs of ram. So, if anyone has a solution, please post! Thank you!

Any other video works. I tried launching vlc with --no-video and then sound channel works. Both totem and vlc gives Segmentation Fault in terminal.
I remember when I installed vlc, it asked whether I will use gstreamer or phonon, I did choose gstreamer. Now I tried reinstalling vlc and it didn't ask for that anymore.
Ok, I tried opening other mkv files and they worked (I don't know why all the time I thought that the file is 100% ok, apparently it wasn't). But that file was similar to any other files (just a new episode of one TV show).
P.S. I noticed that I can open that file with Windows and there are audio bugs, but It shows video well... Ahhh, the most important is that video codecs are fine on my arch, so let it be so!
A strange bug, but if it's like that only with one wrong file, then it's ok. Sorry about bothering you here about my strange file

How can I play mkv files in iTunes?

Hi All,
How can I play mkv files in iTunes?
What're the limitations of iTunes? I see there are a lot of files that iTunes cant play. Is it true for all?
Lofty

BUT my iMac does not support my WAVE files
Sure it does.
File -> Add to library and select the folder where the WAV files are located.

Playing MKV files with a burned DVD on BDP S470

I have found that my player is compatible with MKV files. My question is can I play them back on a burned disc? And if so, do I just burn the MKV file to the DVD like I would any other file(s). If not does anyone out there know the correct procedure and proper softwarefor taking the MKV files and transferring them to a DVD so they play in my player? Right now I use imgburn for making duplicates of my DVD movies for my personal backup. I would like to do the same with my BR movies especially the ones that require a double layer BR which right now cost wayyyy too much. I just want to convert so it can fit on a single layer BR
thanks very much

Stor.e TV + - playing .mkv files have sound but no picture

I've just transferred all of my .mkv files onto my store TV + but most of them have sound but no picture?They play fine on my PC...
Also,anyway of changing the icon on the folder to the actual dvd cover on the store TV +?Sick of looking at yellow folders!!
Thanks..

Hi
Found the StorE TV+ specifications on this Toshiba page:
http://www.toshiba-multimedia.com/eu/store-external-hard-drives/tv-plus/
The Store TV+ supports the video formats:: MPEG1 (DAT, MPG), MPEG2 (VOB, MPG, TS/M2TS/TP TRP), MPEG4 (AVI, MP4, MKV), VC-1 (WMV), H.264 (AVI, MKV,MOV, MP4), RM/RMVB (RM/RMVB)
The MKV files are supported by MPEG4 and H.264 video format.
Are the files recorded in this formats?
How about playing other files i.e MPG or AVI?
Furthermore I would recommend checking the connection to the TV.
Here is a user manual which I found on the Toshiba page:
http://www.toshiba-multimedia.com/Global/Manuals/Store/Manuals/STORE_TVplus_User_Manual.pdf
It shows you how to connect the Store TV+ correctly.

Front row to play mkv files

Is there any codec to make this happen have tried perain and still doesnt work.
Thanx in advance!

MKV files are a bit tricky to get playing, VLC might do it but I doubt that'll help frontrow, it might be worth using handbrake to re-encode these files into MP4.

Toshiba 23EL933 doesn't play MKV files

Hi,
three days ago I bought a 23EL933 TV on Amazon.it.
I tried to play an MKV file but it doesn't work: the movie seems to start but, after one second, the file stops and I come back to the root directory of my USB pendrive.
Is the TV defective? Do I have to send it back to Amazon.it or do I have to bring it to Toshiba Assistance?
Please let me know.
Thank you.
Regards,
Luca.

Hi Lucamarc.
The specifications state support mkv files.
Check if the file has a frame larger than the standard FullHD (1920x1080) and it is bi-lingual.
I have an 32SL833 and I had to re-encode some.

Playing .mkv files

I would like to play .mkv video files, but I have no codecs to make them work on my Mac. I tried using the latest version of the VLC player, but even that would not run them properly. Does anyone know of a (free) player or codec I can use to make them work?

No Sound playing AVI files in Quicktime Pro - help!

Help! I just bought QT Pro for Windows(Xp) to convert my AVI files to Mpeg4 for my Ipod. The Apple Store sales guy promised it could be done. I see video but no sound on all of the AVI files. For example, on 2 of my AVI video files, according to Gspot, the video codecs are "divx 3 low motion" and "Xvid" and they are installed on my pc. According to Gspot, the audio codec required is "0x0055(MP3) ID'd as MPEG-1 Layer 3" which can play on
--> {Fraunhofer IIS MPEG Layer-3 Codec (advanced)}
--> {MPEG Layer-3 Decoder}
which are both installed on my pc, yet I have no sound. I am stuck! The bit rate is 128. Should I be using another audio codec??? Where can I get it? Help! Anyone?

Some of the avi files created on PCs use variable bit rate mp3 souind. QT will not play that type of mp3 in avi files.
One way to deal with the issue is to convert the mp3 to a QT-friendly format. You can try this process, using this freeware Windows program: VirtualDub
Open the problem file in VirtualDub. Set the Video mode to Direct Stream Copy. That will copy the video to the new file with no change. Set the Audio to Full Processor Mode. Then set the compression to IMA compression. Now use Save As Avi in the File menu to make a new file with a new name. Since only the audio is being changed it is a fairly rapid process.
One last thing. To do this you do have to have the Windows codecs for those video formats installed. That is, you have to be able to play them in Windows Media Player. QT uses completely different codecs.

808 Pureview - Playing mkv files larger that 2GB

I have found that mkv video files I have which are larger than 2GB will not play on my new 808. They play absolutely fine on the N8. I have tried with both Fat32 and exFat file systems on my 64GB microSD. Anything smaller than 2GB is fine. Anyone else found this? Is this a problem with the video player in FP1?
Solved!
Go to Solution.

@Roveel
Fat32 file system only supports file size up to 4GB, have you tried a mkv which is between 2gb and 4gb?
Also your micro SD card is most likely formatted in fat32. To have files larger than 4gb please re-format your memory card to use NTFS which you can do on a P.C

Volume increases suddenly during the playing *.mkv file in VLC player

I watched video in *.mkv by using VLC, when video has reached particular moment, the volume (not in VLC) increased from ~20% to ~75%.
This is not VLC's volume, I don't know how to name it correctly, it's volume that I see when I wrote "alsamixer" in terminal.
I replay this video again, and in the same moment, the same thing with volume occurred.
How to avoid it?
At least, I'd like to set some "maximum", because when volume sets to 75% it's become terrible loud.

I've just tested this file in gnome-media player, this problem didn't occurred (!). So, it seems like VLC problem.
The video doesn't have chapters. This file is 3rd series of some tv-show. The previous two was ok (without volume problem).

Ah, volume normalization. Yes.
MKV's (not ".mvk"), or "HD" movies usually have moments when explosions or gun shots are amped up. This is a cinematic effect, best felt with a proper audio system. Go to Preferences - Audio - Effects - Normalize volume to ... some_value (depending how flat you want it). I usually use SMPlayer with Right click - Audio - Filters - Volume normalization.
I did this settings, but it didn't help.
Also, I've tried to replay this video a few times, and found that volume increases in random moment, usually in the beginning. VLC's volume was still the same.
ps: Sorry about wrong format, i've changed it to .mkv
