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.
