Heh, well, I wasn't sure when I read it over, so =)

Someone else had said they were really unhappy with the recording quality of 
their built-in soundcard and just bought a cheap sblive to replace it.

Well, xawtv isn't doing stuff like pulling program info out of a database, 
verifying that the channel actually exists, and most importantly, it's not 
recording and playing back that recording =)  Most of the delay is waiting 
for the record threads to get a little bit ahead of the playback threads..  
There's a couple usleep() calls in tv.cpp that you can remove to speed things 
up a bit, but then you'll be playing back _right_ behind the recording, and 
that doesn't work all that well for some people (though it does for others).
