Good idea. I just tried it and 'mplayer filename' plays all the files successfully except one (which does cause a crash), and adding -vc ffmpeg12 plays them all successfully. I do get lots of warnings and the video displays just the left half of the image, duplicated twice, with a pink bar down the middle of the screen, but maybe this is because the image is too big to fit on the screen and I'm not giving mplayer the correct parms? Ok, yes, I just tried it with -vf aspect and it looked much better.
Anyway, so it doesn't seem to be a problem with ffmpeg. Wait, new info. As I was typing this, mplayer got to the end of the recorded video and then crashed with a signal 11. In Myth, the crashing occurs before it starts to display any video. Does Myth scan the end before it starts to play back?
Any other ideas?
