I have not no problem "per say" (see below) with A/V sync and have used
two different HW sets with different SW configurations.
On my Athlon 1800, ATI Radeon 7000, Audigy (+ OSS drivers:
opensource.creative.com) I have two linux distros:
*With RH 7.2, I must use -framedrop to get good results (yes, even with
this beefy HW! Don't know why.)  Not many frames are dropped, anyway, but
still strange.  Possibly could have used -delay instead. Never tested and
now this box is out for repairs.  Compiler was gcc 3.1
*With Drock 1.6 (www.rocklinux.org) everything works perfect.  No dropped
frames, perfect A/V sync. Compiler was gcc 2.95.3.
Can give more specs on each distro if desired.

On my PIII laptop, ~650MHz, PCI Cirrus Logic CrystalClear CS (module name
cs46xx BTW), RH7.1 (book version). I DLed the .rpm s for MPlayer 0.9pre4,
so perhaps its unfair to compare binary and source versions.  At any rate,
things work fine with no frame-drop and good A/V sync.  Admittedly, I have
800x600 res on this system and 1600x1200 on the Athlon.

In both cases I use fullscreen with the xv driver, as this seems to give
the best results.
