When I play DVDs, the audio comes out off-sync. I have the latest CVS version, as of last night. The sync offset is the same when i use -vo dxr3 or -vo xv. (I have a Hollywood+ card). I also use the sound-out of the Hollywood+ card as my sound output, since i have no sound card. DiVX works just fine, though. The command I am using to play DVDs is: mplayer -dvd 1 -vo dxr3 -vc mpegpes (for DXR3 output) or mplayer -dvd 1 -vo xv (for xv output). The sync seems to get better when i use -mc 0, though it is still noticeable. It doesn't improve when running as root to utilize RTC timing. I am using: Redhat 7.2 with kernel 2.4.18, libc 2.2.4, XFree86 4.1.0, gcc 3.02, GNU ld version 2.11.90.0.8 (with BFD 2.11.90.0.8), and GNU assembler 2.11.90.0.8. /proc/cpuinfo: processor : 0 vendor_id : AuthenticAMD cpu family : 6 model : 1 model name : AMD-K7(tm) Processor stepping : 2 cpu MHz : 605.972 cache size : 512 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat mmx syscall mmxext 3dnowext 3dnow bogomips : 1209.13 I am using an NVIDIA Geforce2 MX (Hercules 3D Prophet MX).
