[QUOTE="Tech Geek, post: 37065, member: 18181"] Give me another 10 hours in a week and it's no prob! LOL I'll do some more recording to satisfy a hunch... there is a possibility it has to do with *how* it was recorded rather than the source video resolution. I won't be sure until I can test more. First... not multipath at all. Watch HDTV has no problems on the channels involved and signal strength is excellent. I'm less than 10 miles from most of the stations and only a very weak religious channel causes problems and turning the antenna fixed that. So that's one issue down. I think the ATi tuner is pretty decent as far as multipath goes anyway. Ok... on the HDTV res stuff I looked at it was a dropped frame here or there. Usually durring motion. I can see that if the video card is to blame so this card *might* be borderline speed wise. The SDTV was more like the latter but I'm sure it's not the signal. Well... I think it may be the way VMR 9 renders. Since it's using 2D or 3D textures... that may very well be the issue. When it decodes 1080i it just stuffs it up on the screen without scaling because it doesn't have to. With SDTV res it has to scale every frame unless it alters the output resolution to match. Not only does the card need the bandwidth to transfer the video data but then it has to have time for the scaling. That would make the 10MB/s a requierment to feed data to the card in bursts. Without seeing the guts of the DirectX code I couldn't be sure. If Microsoft wanted to improve it they probably could though. To avoid this may just require changing the screen res to match the video source. Which may or may not be possible without directly looking at the video stream. I don't know what info VMR 9 provides. For all I know, Media Portal already does this and it's an entirely different issue. Just throwing ideas out there. I'll take a look at it as soon as I can but work has me busy til Saturday and then I may be out of town. I do think the ATi card has the ability to encode MPEG in hardware though. It would just require the ATi NDA and all that goes with it to find out how to use it. So that means I'll need to be happy with software encoding for some time. LOL I have a Sempron 64 2600+ and if I overclock it even a little I should easily make the suggested speed of 2.8GHz. People are pushing these above 3000+ all the time. [/QUOTE]
