I have been using my 770 for a while now to watch BBC video podcasts, and it works great, they are in mp4 format, and work great in the normal 770 video player. Now i download the CNN podcasts that are in m4v format and they do not open in the stock video player, they say that the video format is not recognized or something like that. They also do not open in Mplayer, but if i change the file format from .m4v to .mp4 they will open and begin to play but are super choppy and i cannot even get the other video podcasts that work fine to play at all, they just show a blank screen.

Any thoughs, i have the most recent version of Mplayer and i have no other applications open...

Looks like a poorly supported codec (you can check more information by pressing 'Report' button after video playback attempt in GUI frontend).

MPlayer uses a lot of hardware specific optimizations to be fast. It has excellent supports for almost all codecs on normal desktop PC's (using Intel or AMD x86 cpu) as it has optimized code for most of them tuned during a long time by many people. Internet Tablets use ARM cpu. This different cpu architecture requires its own optimizations, so many less popular codecs don't have ARM optimized version and have to use generic code and perform poorly.

The best supported codec for video is mpeg4 (divx/xvid) and its variants such as flv. It is also highly recommended to use mp3 audio. Other audio codecs may introduce serious performance problems.

ah, well thanks for the info, is there any way i can get the m4v codec for the stock 770 video player, or am i going to have to re-encode everything anyways?

You might want to look into Orb Networks. I found it would translate wm radio stations to pls format, maybe it will do the same for podcasts ie. convert "on-the-fly" to something the 770 will play.

Are you trying to play the video through a shell with mplayer? If so, what are the options you are supplying with mplayer?

Please excuse my ignorance if this is not what you are asking, but i am just throwing the video on a memory card firing up MPlayer, and selecting the video and playing it.
