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. |

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, |
