Bob,
I haven't started config on mythtv yet. It takes forever for Firefox to
start, I couldn't imagine mythtv doing much better.
I assume by buffer card you mean the capture card I have? It's a PCHDTV
HD3000 card. The guidance I have found states the drivers are in the
kernel.
If you think moving it'll help let me know.
