Is this to be expected? i have tried different options in the playback settings but nothing seems to decode it.

I can confirm that problem. It happens here with x264/AVC encoded files. No matter if the source is a PAL or NTSC (after inverse telecine to 24p) DVD.

One more observation:

CPU usage is at about 44% on my C7 which is about right (about the same number I had seen before when playback still worked).

Any more info I can provide ?

I'm also out of luck playing h264 720p50. I'm using stable 20.2 though, but I guess we need ffmpeg resync to be able to play them in mythtv. When I playback the stream with latest mplayer (svn) it works with about 70% load on a AMD 64 X2 4200+ processor (you also need '-lavdopts threads=2' to utilize codec and cpu)

Well for me with a core2 duo at 3 ghz and a 8600 GTS it played quite ok before the vid-merge, now i just get prebuffer pauses and black video and after a while it gives up.

With SVN 14599 it plays fine again using XV Good work who ever fixed this :)

Not sure if this is related or not, but I had this problem as well. I think it was fixed in changeset [14599]. After I moved to a SVN release 14606 playback of H.264 videos with the Internal player started working.

Resolution: fixed

This was probably fixed by [14599]. I just wasn't aware of this ticket.
