Poor SD Performance on HVR-1600

[EdwardATeller]

Last night, I noticed the SD on my HVR-1600 really sucked. Since installing it, I had mostly been watching HD with it, but I decided to put it to the test last night on our critical Thursday night lineup. Recording HD and SD at the same time, the HD looked fine, but the SD was overexposed, washed-out, and stuttery. As a check, I put my old PVR-250BTV into a free PCI slot, disabled the SD tuner on the HVR-1600, and recorded some SD with the PVR-250BTV. Much better.

Have other people noticed poor SD recording quality with the HVR-1600? Are there some tweaks that will improve the PQ? Thanks.

You can try these new HVR-1600 drivers I found:

Thanks. I might give them a try once they are released. Hardly ever have to record two SD at once, so having the PVR-250BTV is a fine solution for now, but I was curious if this is a well known issue. I searched using the terms in my post title, but nothing came up.

Ive always thought my 1600 had good SD. Better than that 500's that are in the box and better than the 250's they replaced way back.

I did move up to the new 1600 drivers, and they seemed to help some HD stuttering I had on a couple of channels! I didn't notice any improvement or degraded performance on SD.

Thanks for the feedback. Maybe I'll play with the drivers, but out of the box the SD definitely is bad. My wife even noticed it.

agree with you, the SD capture is not so great. The picture is a little washed out.

So I guess this is a bit of a bump, doeas anyone know of any way of tweaking the 1600, like the 150 has?

If you go into setup tuners theres an option for color correction, ive never tried playing with it but you may want to give that a try.

Need to bring this post back as I am having problems with stuttering SD video on my HVR-1600. QAM is smooth as silk and crystal clear, but SD is terrible PQ and stutters horribly. At first I thought it was because I was recording QAM and SD shows simultaneously on the same HVR-1600 and was stressing the box, but that wasn't it. I confirmed this by only recording an SD show and got the same results. It also stutters watching live TV as well. Again, QAM is working fine. I'm running Sage 6.4.8 on Celeron 2.4ghz XP2 server with 512mb and 9600 ATI card. I'm using the most current hauppauge drivers (1.62.26028.0) and Nvidia decoders.

I'm not concerned about playback on the Sage server as I'll soon be using Client and a Media Extender for viewing, but this seems like a capture issue. Any thoughts are appreciated.
