Well, it does vary by a bit. Some are not quite so far off. I did find
this little tidbit of info in 'console' under view. This is interesting:

**** 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, my AMD 2500+ with 2GBs of ram is to slow? I know this is a older
rig but surely it ain't that slow. o_O
I also realized something else that may contribute to this a little. I
started a emerge last night and thought it would be through by now.
It's still running. It's compiling OOo and some KDE stuff. Could that
slow things down a bit? Everything else seems to be responding fine. I
have portage set to a lower nice level than my desktop. I even have
ionice set.
Ideas?
