|In testing and by recommendation from matrox, converting to Targa solved the problem all together. |} * T Gipson says: {| border="0" style="background:#efefef;" |I run the RT.X2 on Vista Ultimate 64 with Vista SP1 and it runs fine. It was a clean install and I had to install several times to get it exactly right, but it runs well now. My recipe that finally worked.1. Clean install Vista and updates.2. install Premiere 4.0.13. install Premiere 4.14. install 3rd party plugins- Red Giant, New Blue, Neat VIdeo (ones I have)5. Then install Matrox 4.06. Then install Matrox 4.1 update |}
