Maybe try with recent mplayer (from svn).. and give it "-demuxer lavf -lavdopts fast:threads=2 -no-correct-pts" or something similar.. you can also try with threads=4 etc..
"mplayer -demuxer lavf -lavdopts fast:threads=4 -nocorrect-pts ..." gives steady but slow motion (roughly 50% speed) video. It is weird that the load on CPU1 and CPU2 is less than 40% during playback according to gnome system monitor. Somehow mplayer is not able to max both CPUs close to 100%.
Just tried a sample of DVB-T YLE HD (720p50) on my computer..
It seems mplayer is not able to use multiple threads, at least on my system.. I just see a single process/thread taking all of the CPU.
I guess there's still something to fix for a proper multithreading for h.264 decoding in mplayer/ffmpeg/libavcodec..
I used:
mplayer -demuxer lavf -lavdopts fast:threads=4
