Pixilation(?) on Timeline

I do hope someone can help - and that it's a fairly straightforward solution.

I'm using Vegas Pro 10e and have suddenly found that events that show correctly on the external monitor when viewed from the Trimmer develop what I can only think of as pixilation when viewed from the Timeline (usually blocks of squares such as those you sometimes see on TV when they went to hide someone's face) or general unvenness (as though looked at through a lace curtain).

Initially I though that this might be because the events were taken from a DVD via DVD Shrink but it is now happening with other events (although not with those imported from the DV Tape in my camera), including, for example, titles written using the old standard titling tool.

I've confirmed my project settings are as normal and am working with PAL Widescreen 720 x 576 at 25fps. Changing the settings such as field order etc seems to have no effect.

Thank you.

Right click on the preview monitor, and uncheck
"Scale video to fit preview window"

What preview quality do you use?
I get bad scaling when using preview (half),
and have great result with good (half).

Thank you for your helpful note. It's very much appreciated but...

I'm using Preview(Auto) and changing this seems to make some difference but without solving the problem as some of the pixilation I mentioned remains.

I've disabled "Simulate Device Aspect Ratio" and this seems to help although I'm still left with what I can only describe as jittery edges where sharp lines such as those marking the end of a building are involved. Unchecking "Scale Video to Preview Window" appeared to have little if any effect.

The problem is that I have used Pro 10e for several years and for many projects but have never seen this before as everything has been properly sharp until now.

"Auto" means the image size sent to your monitor is whatever dimension it displays at in the preview window.

Use "Full" instead. Or increase your preview window to a non-scaled display size.

Thank you Rob.

I think we're winning.but when you suggest increasing the preview window to a non-scaled display size is that the same as unchecking the "Scale Vide to Fit Preview Window" button? If not, how should I go about this and do you have any guidance to offer about the sort of size that might be appropriate (at least as a starting point)?
