QAM digital channel switches to analog

[jtlindee]

Hi,

I have a PVR-150 tuner (analog) and a Hauppauge 1250 tuner. I have the digital tuner listed as the "first" tuner in my recording inputs.

However, sometimes, not always, when I tune to an HD channel it will use the digital tune for 1-2 seconds then switch to the analog tuner. I have not been able to determine why it is donig this. Any ideas what I might not have correct in my configuration?

Here is an example of what the log file looks like when it does this:

Thanks in advance for any help!

Do you have a recording starting within 10 minutes on the digital tuner? When you have multiple types of tuners, BTV predetermines what tuner to use for recordings and makes sure that tuner is not being used 10 minutes before the recording starts.

Do you have the QAM channel set to the same channel number as the analog channel? That can cause no end of grief....

your cable company should have 2 instances of each local HD channel... one in standard definition (channel 6, for example) and the same channel in high definition, such as 706.

Your QAM card should be set to the same channel number as the HD channel, not the SD channel. In my case, I use 706 to watch the HD ClearQAM version or just 6 to watch the analog SD version.

Interesting.

I have my QAM channels set the same as my analog channels. So if the program is on channel 5, say, (a local HD channel) and I have an available tuner, it is in HD. If a QAM tuner is not available, then it is in SD.
