Poor Video Quality - Live TV & Recording

[Naynesh]

Hello,

I am using a hauppauge roslyn/blackbird pvr-250(mce?) on regular windows xp with the proper wintv 88x video capture drivers.

My video card is an AIW Radeon 8500DV

Also, using elecard mpeg 2 video decoder with dxva mpeg mode A, dxva interlacing - bob and weave, vmr9 video renderer, dscaler enabled, technique plugin - adaptive, double and odd field both disabled.

Problem I am having is when watching scenes with fast action/pacing (like football) the video quality is very poor - small squares that eventually clear up once the fast moving scenes have stopped.

I have not modified anything and desperately seeking help to try and get this fixed - I had tested with beyondtv and don't have that issue.

I have this issue when using the sage tv client or when local on the server watching live tv.

any help would be most appreciated

The default recording rate is 2GB/hr. You will most likely want to change the recording quality setting to a higher rate. From the Main Menu, go to Setup -> Detailed Setup -> Multimedia tab -> Recording Quality -> Select the adjacent button. In the pop-up list, choose somethign like Best (3GB/hr), or even one of the higher settings.

I was able to easily tell the difference between 2GB & 3GB per hour.

Well first off, Elecard does not support DXVA so you should not have DXVA MPEG Mode set to something other than default (I'm surprised it even works). Same applies to DXVA deinterlacing, plus you don't want the deinterlacing done in the decoder since you're using the dscaler filter.

Also, I would not use VMR9 on your video card, it's not DX9-class therefore can't do VMR9 properly, you'll almost certainly get a better picture with Overlay.

And you also need to enable double framerate (or whatever can't remember off the top of my head what it's called).

Sounds like macroblocking, you need to increase the default recording quality. Try 3GB/hr to start with.

get a decoder thats supports DXVA

DXVA deinterlaces very well and the blurring from software decoding is greatly decreased

Sonic DVD decoder pack deinterlaces very well with DXVA enabled and the overlay rendering picture quality is very good
