I think this is the correct list since the slowness is inherent in
mplayer itself. Also I'm using the latest CVS sources in addition to
released versions. Xine handles this file acceptably, why not
mplayer... Please tell me how to debug/profile mplayer playing this
specific file: At least I can try to find the cause of slowness using
the debugger/profiler.

As written in my previous mail, the worst result were with two boxes
equipped with DVD players, fast enough for most applications. One of
the DVD-ROMS is an LG DRN-8080B with 512kB cache, 24xCD-ROM, 3.6 MB/s,
8XDVD-ROM, 10.8MB/s, access times: DVD - 130msec, CD - 120msec. DMA is
enabled as reported before.

I would not call this slow-seekable media, you cannot find so much
faster DVD-ROMS on the market (twice as fast can be found, but I don't
think the problem is in the hardware, more likely the software...)
The processor speed is 1GHz. This would be sufficient even for a
non-interlaced avi-file, or...
