Ghosting is a known problem with DVDrecorders (I think PCA has experience with this, I know he has had a few set-top recorders)
To answer the question, ses, my current releasing is from Scifi channel on sky digital (see series section of scifi.dead-donkey.com , Babylon 5: Crusade). I also capped league of gentlemen S3 and have got Indiana Jones: Demons of Deception on my pc for encoding.
I have experienced slight ghosting capping from sky too, but I believe it is from the deinterlacing filter I was using. The same effect you can get from terrestrial tv too.
Football looks bad on sky since the bbc doesn't send enough bitrate in their feeds btw. I don't have sky sports so I can't tell, but BBC could really do with upping the bitrate on some of their shows. I've noticed some of the channels don't seem technically knowledgeable enough about video formats and transmission, which is one of the most stupid things I can think of for a TV station employee.
I do not have the movie channels (I've got or seen most of the movies shown), but its worth pointing out that they are encrypted a lot... you need to make sure you are macrodecoding
