Hi,
I have a WD HD 1st generation with latest firmware.
Works fine with 720p mkv files on my Samsung Plasma and JVC surround Amplifier for DTS and DD.
But for 1080p it starts stuttering and stops with an srt file seperate.
So I read somewhere when you mux in the SRT file you should not have that problem.
On my iMac I have mkvtoolnix and muxed in the srt file fine but when I play the movie on my WD HD I have no sound anymore.
Any idea ?
thx
Can you post the MediaInfo for the 1080 file with no audio?
Hi, can you tell me how to do this ?
Thx

There’s your problem.
The WDTV’s won’t handle compressed headers in Matroska files.
Version 4.1.x of mkvmerge added compressed headers to the audio tracks by default.
Version 4.2.x of mkvmerge and newer, add compressed headers to both the audio and the video tracks.
What you need to do is re-mux the file with mkvmerge.
Either use v4.0.x or earlier of mkvmerge which doesn’t do compression by default, or make sure you select “Compression – NONE” under “Extra Settings” for both the audio and the video tracks if you’re using v4.3.x
Thanks a lot,
I have version 4.2.0 for MKV Merge for Mac OSX and indeed I can select ‘None’ for the compression.
Again many thx
You’re welcome.
Just remember to select “none” for the video track as well, even though it’s not compressed in your existing file. Your 4.2.0 will compress the header for the video by default, as well as the audio, so if you just select “none” for the audio track, you’ll end up making a file that won’t play at all.
Thx again, I have another question.
Most of the 1080p mkv movies are 1920 x 816 and not 1920 x 1080.
Is there a reason for that ?
This means on my plasma Samsung most of the time I have not full screen.
But it is possible, I have 2 movies with full 1920 x 1080 in mkv format and about 8 gb.
It all depends on what is used to encode the videos.
Most encoders will use the aspect ratio to decide what actual resolution to make the final output file.
Even DVD players (except for the earliest ones) do this… if a 720x480 file is marked as being 2.35.1 then the DVD player will output a 640x480 “picture” (or a 720x480) but the movie will only be 640x272 letterboxed in the center of that on a 4:3 screen, and 720x306 on a 16:9 screen.
The only aspect ratio that will completely fill a 1920x1080 screen is 16:9… any other aspect ratio and you will either have black bars top and bottom, or black bars at the sides.
Note however, that the HD image, even letterboxed, is still 7 times as many onscreen pixels as the SD version (1920x816 vs 720x306).
Again thx, last question, I have the first generation of the WD HD and it’s working fine for 720p mkv movies.
For 1080p with subtitle seperate it starts chunking and with the subtitle muxed in it plays as good as normal.
Is it known by you that indeed the first generation WD HD has this kind of problems due to lesser cache memory ?
