What kind of CPU do you have and how high is CPU usage. I was just playing around with xvid (I have no experience with it) an mencoder, but 1080i is not playable for me anymore. I have an Athlon XP@2.2GHz. The mpeg2 file is no problem though. I will try your setting, though.
well I've got an AMD Athlon64 3000+, CPU load during encoding is 100% ;-), while replaying I got different values with gmplayer (about 50 to 60%) and xine (100%, dropping frames, sometimes missing audio). With the original mpeg2-file (*.vdr), xine is able to play audio too, but CPU-load is similar. So far I don't know why xine is 'slower'. It's the first attempt to record and play HDTV-material.
My observations are the same: xine needs a lot more CPU to play hd content. Nevertheless I fried your ffmpeg paramters and beside the need to patch fourcc for me, it is not better. Even worse: I suggest using xvid, as picture quality is worse with ffmpeg's codec for me.
Interesting that your athlon64 has so much more horses than my miserable xp - even though my XP should have a higher clock rate than your cpu. :-( Or are you hw accelerating your output? Ie I only have a geforce4 ti4200 which cannot do idct and even gets slower when doing mc.
Are using a 32 bit or 64 bit os?
