- Hmm. I forgot to mention that this problem occurred only recently. My
- GS video was generally centered before, as was NTSC video. I'm not
- sure if it's related or not but when I first got my hands on a VOC I
- noticed that 3200 pics wouldn't display properly. Since I got
- DreamGraphix, I've had the NTSC video out plugged into the VOC input
- to synchronize some video chip. After a few months my GS video
- started to slide over to the left, in fact it went past the edge of
- the screen so I couldn't see the left part of the screen. Since then
- I've disconnected the GS NTSC video out from the VOC, but my GS video
- still not centered.
-
- Now that I've moved out of the house I only took the neccesities
- (sp?) like my GS. I had no TV for over two months, so I had to drive
- over to my friends place every week to watch Star Trek: The Next
- Generation. Of course my friends father has been dropping strong
- hints that I should get a TV. I decided to get a VCR instead for
- versitility, so I could watch TV via the VOC on my GS. Now that I
- have had this set up, I noticed that the video isn't centered either,
- and I'm getting a little frustrated, and worried. I'm hoping that I
- can adjust something on my VOC to correct this problem. The only
- other alternative is to give it to a local Apple repair despot, and I
- do mean despot. Knowing what Apple dealers are like now, I may never
- see it again.
