Issue with blocky graphics

Greetings. I am seeing an issue that I thought I would run by the everyone here. Hopefully someone knows what's going on.

I have been working on a trailer for a client and the client brought in some hi res Photoshop PSD's. I import them to the time line in v8 and they look great. I output the file using the vegas codec and the standard 4:3 ntsc avi template included and they play fine in most players including media player but when I bring them back into vegas(6-7 or 8 as I have tried them several machines including the clients' as they have vegas 6) these files preview very blocky and distorted. I thought it was just the preview so I bumped it up to full instead of auto and it still looked bad. When I output from 8, if I don't make a change it outputs again fine, I think because of the no recompression algorithm. However, if I cut it an add a transition to force it to rewrite the file the "blockyness I see is now written into the file and it shows up even in media player. Deos anyone have thoughts as to what might be causing this. The client is thinking the quality of the vegas output is bad since they tend to view it in vegas, but the blockyness first appears only after the file is brought back into vegas.

Any help/thoughts will be appreciated. Bryan.

What are you bringing back into Vegas?
Why are you bring them back into Vegas?
How high is "hi res"?
Change them to PNGs and drop the resolution down to see if that helps.
Make sure they're not in CMYK format.
BTW, I've done this numerous times with both hi res PSDs and EPSs and they've always look OK to me on the output.

Hi Mike, thanks for the reply... I have used many still pics in projects myself and never remember seeing this before either. the .PSD's are 300DPI and as I stated they look fine the first time I place them on the timeline. but once I render the file out and give it back to the client, they open it up in vegas and when the playbeack gets to the graphics(they are just text by the way) the looked compressed and blocky. As I mentioned I thought this was just the preview setting but I tried it on my vegas 8 and saw the same thing even with preview maxed out. I need to check if the color space is cmyk, and I will try the PNG suggestion.. the weird thing is this only shows up when the rendered AVI is brough BACK onto the vegas timeline.

gwyador, that's very strange behaviour indeed :-(
The only other suggestion I can make is to try rendering in Best mode.
If you can send me one, I'd be glad to try it on my system and see if I get the same problem.

300DPI tells us absolutely nothing. How big are the pictures in pixels? 320x240? 12000x9000? That's what matters.
