I've applied all the advice I've found but am still desperate for help.
I have not found a video decoder that will both (1) properly display deinterlaced 1080i OTA signal and (2) display video while in timeshift mode or recorded video. The MainConcept decoder that installed with the HVR-950 tuner will properly deinterlace and display a live 1080i signal, but will not display recorded video or video while in timeshift mode. The HCW decoder that installed with the HVR-950 tuner does the opposite---there's terrible tearing of the 1080i signal, but the signal will display (albient with tearing)during timeshift mode. During all of this, my CPU is at about 45%.
I recently discovered that, even though the 1080i signal suffered from tearing while I recorded it in GB-PVR, if I play it back through my recently-installed PowerDVD 7.3 Ultra, the video is perfect (and the CPU is at a mere 4%!). On the configuration page for PowerDVD 7.3 Ultra, I checked the option to use Avivo hardware decoding and Auto Select deinterlacing.
So I configured GB-PVR to use that the PowerDVD7 decoder, but alas it behaved exactly like the HCW decoder--terrible tearing, but displays the video during timeshift mode. Although GB-PVR allows me to configure the PowerDVD7 decoder, far fewer options are available to configure than are available through the PowerDVD configuration page. Hardware encoding is among the missing options.
After more research, I had high hopes for the solution presented here -- http://forums.gbpvr.com/showpost.php?p=2...stcount=18 -- but even with the suggested registry tweaks, the result is the same. Tearing.
Is there a way to get the PowerDVD7 decoder to behave in GB-PVR as well as it behaves in PowerDVD 7.3 Ultra? Is there a better decoder that I should be using?
BTW, I'm using Catalyst 8.8. And my logs are attached. Thanks so much for the guidance.
