photo/wavering

I did a project with photos only. On a couple of events the picture is vertical with quite a bit of black screen showing on the left and right sides. For some reason, during playback, on the right side, the black wavers for a second or so instead of remaining stationary. I have the picture displaying for about 5 seconds. What is causing this and how do I get it to stop.
Thanks

1. Open Pan/Crop for the event and make sure you don't have any keyframes.

2. When rendering to a DV AVI file, click on the Custom button and change the
"Video Rendering Qualit" from Good to Best.

No keyframes with those events. I couldn't figure it out, so I inserted new pictures from the media pool, deleting the old ones and it seems to be fine. There still should be an explanation for the problem though.
Thanks for your input.

1. Why would keyframes cause this problem?
2. After fixing the events by putting new pictures in there, now I have other frames that are doing the same thing. This is strange and I don't think should be happening. It's really annoying to have this keep happening.

If you had keyframes they'd be causing the still to move. Very tiny amounts of motion can cause artifacts as the pixels in the source image are mapped to the pixels in the target frame.
Still doesn't explain your problem though. If you have a still that doesn't fill the frame then what you're seeing is the 'nothing' from the non existant track below. Try putting a track of black underneath the track with the stills but set the black to 16:16:16. This may help. Having a large slab of out of legal black at the edges of the frame maybe upsetting something in the TV. This is only a guess, sure will not do any harm.
The other switch that seems to fix a lot of odd problems is Reduce Interlace Flicker.
You could also try reducing your stills to native DV resolution outside of Vegas.
