Must have been something about the CVS snapshot, i guess, as i didn't have to do
it in latest CVS co.

The CVS co worked out fine from mplayer perspective: see log below. But i have a
jumpy playback because of no DMA. One can still view and follow the videos, but
it doesn't meet expectations of someone who has seen playback w/ DMA.

You guys have been helpful so far, though i should have read the instructions
better myself. 

I don't think speedup options like -cache -framedrop will help. I haven't
noticed much of an effect from them. I'd really appreciate any feedback on DMA
you might have, even though it's a side-topic for this forum:

>From what i understand this is a PATA device on an SATA controller, but it's
just a guess. I have a feeling that this bug is a kind of what i have:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=163418#c15

And the last thing i see there suggests to make a custom kernel. Is that on the
right track?

I tried hdc=ide-scsi yesterday, and i got a scd0 device, but playback was even
worse with that. Perhaps that means that the device isn't SCSI per se, but again
is a PATA device on an SATA controller.

Also, another distro wouldn't be like to help with DMA for this device, would it?

Any feedback here would be welcome, but i'll try asking around elsewhere.

P.S. Successful playback w/ no DMA:

Possible reasons, problems, workarounds:
- Most common: broken/buggy _audio_ driver
  - Try -ao sdl or use the OSS emulation of ALSA.
  - Experiment with different values for -autosync, 30 is a good start.
- Slow video output
  - Try a different -vo driver (-vo help for a list) or try -framedrop!
- Slow CPU
  - Don't try to play a big DVD/DivX on a slow CPU! Try some of the lavdopts,
    e.g. -vfm ffmpeg -lavdopts lowres=1:fast:skiploopfilter=all.
- Broken file
  - Try various combinations of -nobps -ni -forceidx -mc 0.
- Slow media (NFS/SMB mounts, DVD, VCD etc)
  - Try -cache 8192.
- Are you using -cache to play a non-interleaved AVI file?
  - Try -nocache.
