Re: Commodore 1081 PAL screen jitter oddity
I have seen something like this before. I dunno if its the same thing but When I tried watching some DVD's on my PC I got serious interlacing issues which was fixed after altering some settings in Video Lan. Which produced an effect much like yours. Now I don't know how to remedy this for you. But it might be a potential cause of this. So I would check to see what the settings are.
Just a suggestion.
