Strange behaviour when scanning for new channels

#1
Hi,

following situation: Pinnacle Quattro Stick (DVB-C/DVB-T/Analog/UKW)

For DVB-C, I declare in TV-Source-Settings as active:

{BDA} PCTV 510e/520e/802e BDA 2885 TVTuner C

ONLY this one - all others are declared as inactive!

On Cable (DVB-C) I have about 150 TV- and about 80 Radio-Channels

So far fine working.

Now I go outside for watching DVB-T:

first, I disable

{BDA} PCTV 510e/520e/802e BDA 2885 TVTuner C

in TV-Sources and enable

{BDA} PCTV 510e/520e/802e BDA 2885 TVTuner

have an eye on the "C" at the end!

OK, I go to the menu "Channel List" / "Channel Search" / "{BDA} PCTV 510e/520e/802e BDA 2885 TVTuner" and wait, until the transponders are found ...

1st problem: it took too long! On 2 Frequencies were found channels, I stopped - but I am NOT asked, if I want to keep these channels - they are gone and I have to manually scan them later again when I add more.

2nd problem: why are ALL the 150TV and 80Radio channels in the "{BDA} PCTV 510e/520e/802e BDA 2885 TVTuner"-list (caution: it is NOT the device with the "C" at the end!

As I have to chose my device (DVB-T, NOT DVB-C) I CANNOT WATCH ANY any of those 230 DVB-C channels!!! so why the hell do I have all these 230 DVB-C channels in my DVB-T list???

3rd problem: when scanning manually, channel at K33 (570MHz) was scanned wrong so that I only had some technical channel info. I deleted the whole "transponder frequency" and scanned again. Now all 4 channels are found. But when I click on OK, neither the transponder nor the channels are in the list! What do I have to do to get these channels in my list? They come with 100%/100% ...
