I use my 3250HD to capture in Myth.


You have to use some variation of an IR Blaster to change channels.  To
avoid missed channel change codes, I wrap the front display of my 3250
in aluminum foil, and haven't missed a channel change yet.

As for using a Sound Blaster.  I have an Audigy2 and use the firewire
port from it.  I can't seem to get these streams to go output through
spdif for some reason, (I know its not the card since I can output dvd
audio streams through spdif).  I just get crackly undecodable audio
streams in all of speakers.  Software decoding of the streams does work
however, and I just output analog 5.1.
