Hi ATR,
Your info helped me very much:
I am using Premiere Elements 10 on a Window 8.1 Pro 64bit machine (Asus motherboard, Core2Duo processor) with and NVidea Geforce GT610 graphics card. Initially I returned to driver version 327.23 but that did not fix the problem. Version 320.49 (actually for Windows 8 64bit) did.
I did not only fix my preview problems but also the problems I experienced with the font style for the Texts that can be added in overlay to the film.
I only experience the preview problems with HD films. The previews were shown correctly for SD-PAL video!
Regards,
