Effect render Problem with AVID Xpress 4.8 at DVinfo.net

Hi There,

I've got strange problems to render effects with my AVID 4.8 when I work with 16:9 50i SD PAL Material.

Normally I use my system to edit SD 4:3 - no problems so far. But when testing the 16:9 workflow for a new project, hardly any effect apart from color correction could be applied. Just some effects (like the sawtooth transition) are visible, but in a strange, distorted way - as if the takes to be dissolved were interpolated / the picture format was wrong.

My first thought was of course, that may NLE was faulty somehow, and I tried again on a completely different (xpress Pro 4.5) workstation - same result!

It came to my mind that...

a) I failed to change some settings in AVID.

b) the problem has to do with my camera - a CANON XH A1. It has a 'real 16:9' chip, and my -probably naive- assumption is, that it produces a different kind of 16:9 signal, that 'good old AVIDXpress' can't handle.

Please help! Does anyone have an idea?

I know, my mobile NLE is not the newest one, but worked fine for 4:3 SD PAL so far:
