I use a panasonic deck dvd recorder to capture satelite programm,but i have some issues.More importantly,there is an image shiftingphenomenon,that i don't know what the cause of it is,and how to repair it.

A)So how can that be fixed?
B)Also since quality isn't that great,what vdub filters can i use to improve video as much as possible?

I use autogk to convert to xvid.
1)I ntoice it uses audio normailzation.Isn't that bad for audio?Although audio doea become louder than the mpeg-2 source after conversion.
2)VBR audio,means less bitrate for audio?Cause using the vdub calc function that's what it says.
3)How can i completely disable cropping,cause it sometimes does a bad jov in AutoGK.
