Flickering SD video, HDHR QAM

[projectionfreak]

Hi, I'm getting an annoying flicker, like momentary dbl vision. It isn't like a normal stuttering video problem. It only happens on SD channels, HD is perfect. I recently reloaded the computer from scratch b/c I got an HDHR and the HTPC's OS had been on there for a long time and I was having some problems trying to get MVK files working(still can't though) and some misc config problems. Now the only codecs I've installed are PowerDVD 7.3 and DIVX. Bluerays play fine, HD channels, and DVD's on this system. FYI, The cable runs directly from the pole to the HDHR w/ only a splitter at the tuner unit. Works fine in VLC. Is it possible that Sage is trying to use one of it's crappy built in codecs for SD video? I have Nvidia purevideo codec, but I am hesitant to install them wanting to keep the machine as clean as possible. And I was never very impressed with there performance. I also can't get overlay to work in Sage. Any idea's on this would be great, Thanks.

My setup is:

OS - Windows XP Pro SP3

Frontend - Sage 6.5.9 w/SageMC

Codec - Cyberlink PowerDVD 7.3 & DivX

DVD - LG Black Blu-ray/HD DVD-ROM SATA Model GGC-H20L

Motherboard - GIGABYTE GA-MA770-DS3 AM2+/AM2 AMD 770

Memory - Crucial Ballistix 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel SLI Memory

Video Card - EVGA 01G-P3-N959-TR GeForce 9500 GT 1GB 128-bit GDDR2 PCI Express 2.0 x16 HDCP SLI

Storage Drive - HITACHI Deskstar 1TB 7200 RPM SATA 3.0Gb/s

Afraid I don't have an answer but am suffering from the same problem.

I notice the flicker mostly on QAM recordings. I see it as a possible key frame issue. one out of 'x' frames is out of sync, maybe off by one second. in slow moving scenes it is not visible but as scene changes happen you see a moment of the previous frame.

I see it in VMR9, default decoder, set as NvidiaBronze. using windows media decoder utility.
no problem in overlay the rest set the same.
no problem in default (VMR7) the rest set the same.
VMR9,Sagedecoder no issue.

so I will be currently using the sage decoder. but I do think i have tearing issues with it using HD.
