I get the error message "Can not connect video encoder and wmv codec" while starting recording, it records nothing even though the blinking red dot appears in the picture. It would be nice if someone would help me with this problem.

Internet TV? try install last WMP.

No, not internet TV. Viewing normal television channels in 6.04.04 for 64bits.
I can see the channels all fine, I can hear the audio. But when I press record it says this "Can not connect video encoder and wmv codec" every time. No recorded file is created.

I would also mention that I can use anysee viewer to watch television channels AND record normally, but I would prefer to use Progdvb.

You can select not wmv format for record. Or check settings of this format.

I got it to work again. I uninstalled, deleted every mention of progdvb in my registry (there were many even after uninstalling), reinstalled and after that it works normally.
