Can't tune after switching to QAM

I had 1.2.9 on Vista SP1 running with my OnAir GT using OTA. I decided to see what clear QAM I could get with my cable so I set it up as another device and searched. I found quite a few goodies in clear QAM. I can see them (sometimes, the config program seems a little unstable here) in the preview window so I mapped channels. When I go to watch live TV, the screen goes blank for a second, then back to the menu.

Any idea why it's doing this? Attached are my logs.

Also, a couple other questions

1) Is there anyway to hide/disable a tuner? I've got two configs now for my On Air GT, one for OTA, one for QAM, it would be nice to hide the other device when I'm trying to use the other.
2) I'm using SD as my EPG. When I updated EPG after doing my mapping (only about 20 channels) I went in to the channels menu in the config, and I had 150 enabled channels, even though I don't have mappings to them. Why did it enable all channels that didn't have mappings?

Thanks...

Its something to do with have channels enabled in your capture source that dont have the tuning information available.

No, sorry.

Any channels supplied by your EPG source are enabled by default, until you specifically disable them. On a digital capture source they supposed to be automatically disabled when you hit the config app OK button if no mapping has been done for that channel.

I don't understand...They are frequencies that GB PVR picked up during a scan. Although, GB PVR picked up more frequencies than the On Air GT scanner itself did, for some reason.

If you look in your capture source channel lists, I'm sure you'll find an enabled channel that doesnt have any mapping defined (in the tuning request column). Its not supposed to happen (its supposed to auto disable unmapped channels), but your logs indicate that is the cause.

I've gone into my SD account and disabled most of the channels. I emptied the EPG and updated, but they still show up on the channels list, and are still enabled. (downloading the EPG takes a lot less time now so I know they're no longer being sent...)

I'm not talking about the SD end of things. Just go into your capture source channel list (in the config app), and disable all the channels except those that have definitely been mapped (ie those that have something in the tuning request column).

I did that, I disabled everything except for 1 known working channel, and it still didn't tune to it.

I deleted the capture source, but it still didn't delete all the enabled channels for that source, so I guess I will have to delete them manually.

Is there a config file with this channel information I can directly edit? The config program is far to cumbersome to do repetitive procedures with.

ETA: Something else I see happened...It looks like the software inter-mixed the OTA and the QAM capture sources, as the OTA configuration has the channels enabled with no frequency next to them.

Another thing I'm trying to under stand is...The OnAir GT tuning facility and the GBPVR config program are coming up with different frequencies for the same channel.

ie, OAGT has one channel at 92.1, but GBPVR has it at 92.4.

Delete the gbpvr.db3 file, then start the config app and recreate your capture source, then try the whole process again. If it doesnt work for you, post the logs again and I'll see if you're still having the same problem.

I'm sure you're just doing something different, otherwise others would be having the same problem.

Thanks Sub,
I ended up deleting both devices and that seemed to clear things up. It looks like GBPVR intermixed the channels from the two device configurations. Not sure if it's supposed to do that or not. (what I mean by intermixed, is when viewing the specific device, it showed the channels for both devices, not just that one device.)

I'm still puzzled as to why GBPVR and OnAir's own viewer are coming up with different frequencies for the same channel. GBPVR is also listing many more frequencies than the OA viewer is.
