Unfortunately I didn't do my homework before buying the 350, and I'm faced
with the two options mentioned above. I think I'll wait for the 0.2.0 ivtv
drivers, and if they don't solve the problems I'm seeing, I think I may
invest in another video-out card until drivers mature. Jarod mentioned
using a GF4MX card. If I used a similar setup (350 for capture, GF4MX for
video out), would this also solve the ivtv-related problems I'm seeing with
the program guide crashing my system, and truncated/incomplete recordings?
Right now the WAF is about zero, and she's not too happy that I spent all
this money on something that's not really usable. If investing in a video
card would make the setup more wife-friendly, it would be worth it...
