HD2400pro cards work different in HW support used by Power DVD for MPEG2 and AVCHD content. On a Sappire HD2400pro card the AVCHD is accelerated but not for HDV2 (HD MPEG2). On a passiv Gigabyte HD2400pro it is even worse - no HW support on both formats. I would recommend the HD2600pro for HD video on the HPTC.Yes, I use Cyberlink Power DVD for HD content (watch it via MP works great) for my HD 2400.
