Maybe this is well known, but I have found no mention of it anywhere on the net...
With the latest firmware my DSM-750 will play H.264 video in an MPEG-TS container. I use a file name extension of .m2ts (same as Blu-Ray) and a mime type of video/MP2T. You can also include 5.1 channel AC3 audio, although some encoding programs (those based on mencoder) currently have a problem with this although VLC does it correctly.
It doesn't seem to be able to handle the bitrate of true 1080p hi-def (about 30Mb/s) - or maybe that's just my server, (although I doubt it), but 720p at about 12.5Mb looks quite good.

What is happening when you play the files and are you running wirelessly?
H.264 are supported in MPEG-4 Part 10 format you should be able to play this format in 1080p. Matroska .mkv will be supported in the next firmware update which seem to play very well also.

What happens is that playback totally freezes. With a high quality H264 (1920x1080 at >25MBit) playback freezes almost instantly, with lower quality playback starts and gets some way before freezing. It doesn't seem to restart even if left for several minutes, although the player is not crashed as it responds to the remote immediately.
Actually further experiments show that even at 12.5Mbit H264 will sometimes freeze. I have successfully played MPEG2 at 20Mbit and MP4 at 15Mbit so I don't think the problem is networking and I have used both wired and wireless (my wireless is a DAP-1522 on 5GHz with gigabit all the way from the server to the AP).
By the way, you need to get the word out that these extra containers work. The general word on the forums is that H264 has to be in an AVI file! I'd like to see a table on the web of containers vs supported codecs for the DSM-750.

PS, I'm looking forward to the next version of firmware - there seems to be better support for generating .mkv files under Linux :)

.mkv H264 are now supported with the latest firmware 1.02.

How did you get the MP4 @ 15mbit to work? Are you using the 750 as an extender or in medialounge to play these files. I have MP4s with AVC video streams at 1.5mbps that the video freezes using as an extender. The audio plays fine, just during the movie the video will freeze and catch up with the audio eventually. The higher the bitrate the more video freezes. I'm having to transcode these videos using mkv2vob to mpg with MPEG-2 Video streams....

Yeah right. They are only supported in medialounge mode.

Sorry, one more question. If you rename the files from m2ts to m2t will they still play in extender mode? In order for these files to play on my ps3 they have to be renamed...

I only use the medialounge mode.

For support in MCE extender Mode this is something Microsoft will have to address. Has anyone tried this on XBox360?

what container does mkv2vob uses for the convertion from mkv to mpg. i am trying to do the same with xvid4psp but with no success. if anyone knows this soft maybe can throw some suggestions.
-
mkv2vob uses mpeg video (version 2) main@High-1440...
Hope that helps....
