[mythtv-users] a few fuzzy channels

[wmaccormack at comcast.net]

Better yet, I took my card and plugged it into a known good machine, still fuzzy channels.  I also took a known good card and plugged it into my configuration, still fuzzy.  So it's definitely the card, which I don't understand because I just got this thing up and running.  I'm in the process of contacting Hauppauge now to see about a replacement.

Thanks for the info about Comcast.  It may come in useful in the future.
