I'd agree with you there if it weren't for the fact that my Dell laptop
(P3-600, 256M, S3 Savage/IX) which is very similar to the Toshiba seems to
be able to play these clips perfectly fine.
I did some playing around, dropped the X colour depth to 15 bit, and now
have ~15% idle time on my cpu when playing myth recordings. Unfortunately
I'm still getting pre-buffering pauses. Looking at the "-v playback" logs
from mythfrontend I see that the audio begins to lag by a few frames then
the pre-buffering pause will hit. I wonder if there may be a problem with
audio (yamaha chip) or the machine is RAM starved (192MB). Time to dig
through the ALSA archives and hunt for some more RAM for the laptop
(although something tells me 192MB was the maximum RAM this machine could
take).
Still looking for ideas,
