Hi, I've just bought a 36 ich PF2.. I've noticed that my 18 month old Amstrad Digibox is producing vertical lines on most channels (after testing against an old Pace box). I have the option to keep the old pace (mk I) digibox instead of my newer amstrad (mk III). Is there any differece in picture decoding quality between digibox generations or are the improvements generally things like menu speed etc.?
