Hey
MCE can only go as high as ~8mbit according to MS. Which explains why it changes itself back after a reboot. The sync issue is adressed in the MCE HD Update rollup at least it fixed my problems. If you want to improve picture quality i suggest you use a weekend for finetuning.
My rig uses the Pvr-150, Albatron fx5900xt 66.77, nvidia Decoder .67. Crt TV (from sony 720/576 @50hz)(Vpl-cs6 projector@800x600) I am satisfied with my picture on my tv and I am very picky. Projector is another story Damn i hate LCD!
Do note that the resolution is very important, otherwise scaling will be done by your Video card which sucks on my system anyway. Also leave nvidia decoders on the default setting, otherwise you will have stutter and a crapped up picture. The various deinterlacing schemes done on the fly by the decoder is useless in my mind. Should you use the Windvd .6 decoders do increase subpicture precision to 100%
I noticed a vast improvement in picture quality using the Forceware 70+ but my system then becomes unstable, so i use the 66.77 driver. I guess nvidia is pursuing those teenagers which themselves does'nt pay their own electric bill, and therefore buys a SLI systems. All drivers above 66.77 seem to be optimized for SLI. I HATE SLI and the path of Nvidia. 180watts for video processing? Insane!
Another thing is the Hauppauge driver, The newest 23073 driver seems to be very poor, as far as picture quality. I think the 23053 is far better, when tweaked correctly with the hauppauge tweak tool below are my settings
1 in motion blur
3 static temporal
Bitrate 7000-8500 Vbr
Sharpness 5
contrast 123
brightness -5
other setting left as default.
Do remember to REBOOT after using the tweaker. Anyways i hope this helps but my settings might not be good on your system. I've spent hours of trial and error getting my picture just right.
