Hello.

I finally got my TwinhanDTV 1022A working with Windows Vista x64.

ProgDVB correctly detects my card and I set the DiSEqC to none and added Astra 1F, 1H, 1KR, 1L, 1M, which is listed as Astra 19,2°E.

When I perform a channel scan, ProgDVB finds only a number of international channels, however no single german channel is found (I'm german, so these are most important to me).

I tried scanning single transponders, but ProgDVB found even less channels, and they were the same on all transponders I was able to scan.

My dish is correctly set up; I have several digital TV receivers in my house and they all work fine.

I'm thankful for any help.

Try to find out and post some characteristics for the stations you do get, to perhaps give some hints towards the source of your problems.
For example, are they all on just one transponder?
Or all on low band only?
Or vertical only?
...

BTW, you may have to set up device options, to enable full access to your tuner.
