    Mplayer DVD Sound issues

    I'm using mplayer on an Arch system, and when I tried to play a DVD, the sound came out funny. I ran it from the console and got this:
    Code:
    Checking audio filter chain for 48000Hz/2ch/ac3 -> 48000Hz/2ch/ac3...
AF_pre: 48000Hz/2ch/ac3
[AO OSS] Can't set audio device /dev/dsp to ac3 output, trying s16le...
AO: [oss] 48000Hz 2ch s16le (2 bps)
Building audio filter chain for 48000Hz/2ch/ac3 -> 48000Hz/2ch/s16le...
[format] Sample format big-endian AC3 not yet supported 
[libaf] Reinitialization did not work, audio filter 'format' returned error code -2
Couldn't find matching filter/ao format!
    Anyone know how to fix it or what I may have done wrong?

    Did you install the "codecs" package? (Or "win32codecs" perhaps.)

    Apparently it is something related to DTS support:

    Thank you. That is what I was having trouble with, although I'm not sure how I would fix it. Unfortunately, that was a rental DVD and I returned it, so I don't know how to reproduce the error.

    However, while checking other DVD's around the house to replicate the problem, I got new errors! The pop-up alert said "FATAL: Could not initialize video filters (-vf) or video output (-vo)."

    Code:
    Opening video decoder: [mpegpes] MPEG 1/2 Video passthrough
VDec: vo config request - 720 x 480 (preferred csp: Mpeg PES)
Could not find matching colorspace - retrying with -vf scale...
Opening video filter: [scale]
The selected video_out device is incompatible with this codec.
VDecoder init failed :(
Opening video decoder: [libmpeg2] MPEG 1/2 Video decoder libmpeg2-v0.4.0b
Selected video codec: [mpeg12] vfm:libmpeg2 (MPEG-1 or 2 (libmpeg2))

    Hum... what's your video & audio hardware? What is the content of your ~/.mplayer/config file?

    You can view the complete liste of mplayer audio output with this command:
    Code:
    mplayer -ao help
    and test which works better for you (best quality & least CPU usage).

    For video, you might want to test as well:
    Code:
    mplayer -vo help
    For more info on video filters:
    Code:
    mplayer -pphelp
    Some video filters options are tailored for DVD viewing, like:
    Code:
    mplayer -vf pp=lb:a dvd://1 -dvd-device /dev/dvd
    To get the most out of MPlayer, you need a solid config file (subtitles adjustments, video filters, caching, etc.).
