I have used TCPMP (072RC1) to play video podcast from ABCNEWS, CNN, and Washington Post with some success. For some files with extension .m4v (e.g., ABC Nightline, CNN), I've got good audio but poor video with disjointed still frames.
I have installed ffmpeg plugin on my x51v. Are there other video plugins for TCPMP or video players that I should try?
The ABCNEWS video podcasts can be found:
