M780 QAM->NTSC Tuner Fails + Can I manually input QAM channels?

[Boiler98]

Hello all.

Slowly my GBPVR system is falling into line. I'm currently trying to tackle two issues that are bugging me.

(1) When I go from a channel coming off my QAM tuner to a channel on the NTSC tuner, the NTSC channel fails to show up. I can start on a NTSC channel and move among them, but not between the tuners. Going from NTSC->QAM has a tendancy to kill the sound -- I get the QAM video, but no audio.

(2) Scanning my QAM tuner is still not 100% with all the channels. I got all the local channels + a few more once, but since then I a bunch more but am missing several local broadcast stations. I've found a site with frequency information on it -- if I have that information, is there someplace I can manually type it in?

Thanks!

You would need the Video and Audio PID ids for the stream.

I'm guessing you're referring to my question about manually inputing channels. Say I have those... where can I put them in?
