[QUOTE="savaino, post: 481368, member: 26771"] Hi, When watching DVD (ripped to local SATA hard drive in native VOB format with no alteration) during scene panning the video stutters and playback in general is not as smooth as it should be and after a lot of tests/tries I'm out of ideas. My AVCHD in mp4 format home videos in full 1080i play smoothly as butter same for a bluray rip.....(in original m2ts format) here my configuration: HW: CPU: AMD BE2350 Video: ATI: 3450 MB: ASUS M2A-VM 4GB RAM SW: XP-SP3 32bit Mediaportal 1.02 Codecs: Cyberlink PDVD8 hardware accelerated for both h264 ATI 9.6 driver HW acceleration works very well for the AVCH files: both CPU and GPU load is quite low (<20%) With MPEG-2 DVD files (VOBs) the GPU load goes up to 60% while CPU is around 40% not sure why as load it should be even lower than h264 decoding ? Using (shift-1) I can see that for h264 dropped frames are basically 0 and jitter is also >5. For DVD dropped frames are in the hundreds and reported jitter is around 20 or more. I was almost going to update the entire system (CPU and GPU) but after seeing the HD content playing fine I'm not sure at this point if there is any other setting I need to play with....de-interlacing maybe ? Any suggestion on best MPEG2 decoder ? Preferably with hardware acceleration ? I tried SAF but HD is unwatchable and DVD quality did not change much. I disabled AMD Cool & Quit too.
