[QUOTE="ajp8164, post: 417137, member: 64375"] Yeah - I really believe it to be something to do with refresh rates. The difference between TME and MP is huge in how the video is rendered. I doubt TME has anything to do with DirectShow; MP depends on it. The stream coming from the HDPVR is 1920/1080 interlaced at 30 fps. I doubt the TV refresh rate has any impact since it just accepts my VGA output. I suspect that the problem is in the drawing rates in DirectShow as compared to the refresh rates in the HD3200 chipset. If there was a problem at the output then the how MP interface would be stuttering not just the video portion. So this is what I think the chain looks like (feedback encouraged)... (a) 1920/1080i @30 (HDPVR output) => (b) DirectShow scales and the rate is changed to 50 (I think) => (c) the chipset is scanning at 85 (I think) => (d) whole frame conversions to 60 (VGA compatible) => (e) displayed on TV (which is scanning at 60) I think the problem is at the (b) / (c) interface. Perhaps someone who knows more can comment/correct. I'll continue to research this problem. [/QUOTE]
