Hi Everyone I do have a really stable setup except that i have 15 framedrop/sec when watching Live HDTV from HD-PVR connected to a 720p feed from Scientific Atlanta HD4250 and/or 1080i OTA channels. But this problem only occured when my resolution is set to 1920 x 1080. If I set the resolution to 1280 x 720, Everything run Smooth. Do you know if it's an onboard GPU problem or anything else ? I would like to be sure before spending some money for a fanless HD5450 GPU. Of course I can stay in 720p resolution but it's annoying when i want to play 24p source and my resolution goes from 1280 x 720 to 1920 x 1080 24hz. Some bug can occur, even with wait.exe. I prefer to stay 1080p all the time for a smooth hz changing (24hz,50hz,60hz).

thanks a lot in advance guys.
