33 So you are getting 'data', even if it was black. I see in a second
34 email you got a picture now. That's good.

62 You are lucky. You do not have the problem I have.
63
64 OK, since your other email said you got a picture but Myth isn't
65 seeing it please try removing the current card setup in mythsetup and
66 recreating it. I've had a couple of times where an ivtv update caused
67 the existing card settings to not work. I delete them, recreate it
68 from scratch, and I'm back to the races.
69
70 On other possibility is how you are linking the PVR to Myth. Did yuo
71 set the video device to /dev/v4l/video0 (not /dev/video0) and the
72 default input to Tuner 0? In the input connections section did you set
73 Tuner 0 to your cable listing from Zap2It?
74
75 Hope this helps,
76 Mark
