Bryan,
If you run your channel change script from the command line, using xawtv or
something else to view the output (so as to avoid any time-shifted delay
from Myth), how long does it take to change the box? I'm using Directv,
serial, and the http://tarek.2y.net/myth/sony.pl (on a RCA box, go figure),
and it's instant. So you may not need to speed up the script at all.
I'm not sure what capture card you're using, but if it's a pvr-250 I was
able to set that up using VLS (videolan server) to stream from the card, but
I think xawtv can work also if you output the raw stream and not mpeg2.

Takes me about 5-6 seconds for a channel change. I've got a DirecTV unit
with one
of the serial change scripts. I'm going to take a look at that sometime
this
weekend to see if I can speed that part of it up at least, since you guys
have made
some good suggestions in this thread already.
Anyway, here's my file system/stats. DMA is turned on for both drives.
/dev/hda1 / reiserfs notail 1 1
/dev/hda1:
Timing buffered disk reads: 64 MB in 1.13 seconds = 56.64 MB/sec
/dev/hdb6 /home reiserfs notail 1 2
/dev/hdb1:
Timing buffered disk reads: 64 MB in 1.17 seconds = 54.70 MB/sec
