Commodore 1081 PAL screen jitter oddity
Greetings,
Not entirely sure whether this is down to a possible fault that was fixed in a later design or not.. While using the 1081 to watch a PAL DVD (widescreen format usually), the screen will jitter intermittently vertically. Unable to provide any photos at this time that may help describe this. This does not surface when viewing NTSC DVDs. This oddity does not seem to surface at all on a spare 1084s. Anyone else encountered anything like this? What could be a possible cause? |

Re: Commodore 1081 PAL screen jitter oddity
My various model 1084's and 1084s's ALL produce a consistent high-speed jitter when viewing PAL on the 60hz American electrical grid. Are you referring to this natural phenomenon?

Greetings,
I probably should've clarified there. I'm located in the UK, 50Hz here. |

Re: Commodore 1081 PAL screen jitter oddity
Although it has been a while, still haven't been able to find a possible cause as of yet.
I've however attached a photograph to display what occurs. I apologise if my general terminology was completely off. |

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. |
