latest vlc plays audio, while video is frozen. mplayer plays extremely slow.
looking at the details I saw mplayer reports fps: 30 while vlc reports 59.65
file is from Sony AVCHD and should be 60fps. mplayer has correct size 1920/1080 while vlc says 1440/1080

tried setting -fps from the command line , same delayed playback. now the kick in the gut:

scb@scb-Aspire-5250:~/Videos$ mplayer -fps 60 /home/scb/Videos/vid1.m2ts
mplayer: Symbol `ff_codec_bmp_tags' has different size in shared object, consider re-linking

**** Your system is too SLOW to play this! ****

Possible reasons, problems, workarounds:
- Most common: broken/buggy _audio_ driver
- Try -ao sdl or use the OSS emulation of ALSA.
- Experiment with different values for -autosync, 30 is a good start.
- Slow video output
- Try a different -vo driver (-vo help for a list) or try -framedrop!
- Slow CPU
- Don't try to play a big DVD/DivX on a slow CPU! Try some of the lavdopts,
e.g. -vfm ffmpeg -lavdopts lowres=1:fast:skiploopfilter=all.
- Broken file
- Try various combinations of -nobps -ni -forceidx -mc 0.
- Slow media (NFS/SMB mounts, DVD, VCD etc)
- Try -cache 8192.
- Are you using -cache to play a non-interleaved AVI file?
- Try -nocache.

so system is too slow (Ubuntu 11.10), but it plays perfect in Win 7 !!!
hardware: amd dual C-50, amd radeon HD 6250, 2gb ddr3

pls advise if it is possible to check the radeon driver and maybe speed up things with the driver. Ubuntu seems to be much faster than Win 7 doing anything else, I cannot believe video playback should be different.
