[MPlayer-users] DXR3 audio/video sync issues

[William R Sowerbutts]

I am running Debian Woody 3.0, Linux 2.4.18, X11 isn't running.

Hardware is 1.0GHz Pentium 3, VIA ProSavage PM133 chipset, 256Mb PC133 SDRAM,
Sigma Designs Hollywood+ (Sigma 8300 based, "DXR3"):

00:0a.0 Multimedia controller: Sigma Designs, Inc. REALmagic Hollywood Plus DVD Decoder (rev 02)
        Flags: bus master, medium devsel, latency 32, IRQ 5
        Memory at ef000000 (32-bit, non-prefetchable) [size=1M]
        Capabilities: [40] Power Management version 1


Mplayer says:

MPlayer CVS-020719-02:38-2.95.4 (C) 2000-2002 Arpad Gereoffy (see DOCS!)

CPU: Intel Celeron 2/Pentium III Coppermine,Geyserville (Family: 6,
Stepping: 10)
CPUflags:  MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 0
Compiled for x86 CPU with extensions: MMX MMX2 SSE

There are no error messages in the output stream.

GCC 2.95.4
GNU ld version 2.12.90.0.1 20020307 Debian/GNU Linux
GNU assembler 2.12.90.0.1 20020307 Debian/GNU Linux

The problem occurs using either OSS or SDL output, playing a file recorded
from UK DVB-t transmissions, and also with DVDs.
