I'm using a Geforce 6200 and I get that same trash on my screen if I have hardware acceleration enabled for the mpeg decoder. I've tried a couple different codecs and they all do the same thing as long as hardware acceleration is enabled. Maybe a driver issue like sub said.
I am using older NVidia drivers since the newer ones don't seem to detect the component out of my video card. I might try the latest drivers and see if that makes any difference. I'll let you know.
Sorry. I was wrong about the hardware acceleration before. It appears that setting the codec (I've tried Cyberlink, NVidia, Intervideo and DScaler 5) to use Bob deinterlacing causes those artifacts when set to any aspect ratio other than 0,0,1,1.
Is this GB-PVR ? NVidia video drivers (I've tried a few different ones) ? Something else ?
GB-PVR just tells VMR what shape to make the window, literally passing the 0,0,1,1 numbers, then its up to VMR to do the rest. GB-PVR doesnt do any of the drawing itself. If this is generating garbage, I'd guess its most likely the video card drivers not handling the requested deinterlacing method.
I'm having this problem as well, have tried both Nvidia and Dscaler 5 decoders. Using a Geforce 6600. I'll also add that the corruption seems to flick in and out with scene changes.
Problem seems GBPVR centric as can change aspect ration in another DVB viewing application (digitalwatch) that also uses the nvidia decoders with VMR9 without problem.
