Sub has pointed people to mpv decoder in the past

There is a howto linked from the home page

I installed the new codec and it's operational. Unfortunately, it hasn't fixed the motion blur problem.

Also timeshift is the feature that allows you to rewind live tv right? It seems I have to pause/play tv before it becomes operational each time. Is there a way to passively enable it? I tried searching but couldn't find an answer.

The motion blur may be and probably is a deinterlacing problem. It might be hard to track down, but turn off deinterlacing anywhere you can think of. ("Weave" is the same as off.) It might be your video card settings are set to deinterlace and gbpvr config is also set to deinterlace. It's odd, but I swear turning off deinterlacing in PowerDVD made a problem or two go away despite me not using PowerDVD at the time to watch the video. GBPVR may have been using its decoder and that caused it, though. Computers can be strange.

I'm guessing the blur is worse on shows shot on video, such as live sports, but then again maybe not. If it's a minor blur, it could be your video card has some crappy noise reduction or something turned on, (newer ATI cards have that and things get a ghosty look), but I think Nvidia cards you can turn that all off in settings if it's on.

Timeshift is buffering live TV. If it's not on all the time, yeah, you have to pause/play first. You can turn it on fulltime on I think the first tab in config. I forget exactly what the option is called, but it should be fairly obvious.

edit: just noticed you mentioned sports for the blur. Yeah, it's pretty much guaranteed to be a deinterlacing problem. Or possibly some weird 2:3 pulldown problem. Turn all that stuff off on your video card settings and anywhere else you can find it. Can always turn options back on later. If you are watching sports and the ghosting goes away but you see a combing effect on movement, or on a ticker tape moving on the bottom of a news screen, that's good, that's just the picture with no deinterlacing.

untick live preview mode, you can change it in the config app under misc - be aware that channel changes will be slower though.

Personally i had the same issues you do with sports. I installed nvidias pure video decoder and had a play around (finally getting it to go...) and its fixed all my problems perfectly. Try downloading graph edit, and run it whilst playing a recording in windows media player - it should show you what decoders you are using etc - i personally found that even if i did choose decoders in the gbpvr playback tab it wasnt using them, you can use graph edit to see what is actually being used (took me ages to figure that one out....)

Alright I've looked everywhere. I've gone through every GBPVR setting, every NVIDIA setting, and any other setting I could find and was unable to find anything regarding deinterlacing. The only thing I found was that video rendering might have something to do with it, so I installed Enhanced Video Rendering through Microsoft .NET Framework 3.0 to replace the old VMR9. This did not help the problem. I tried to find a way to edit EVR settings to see if it controlled deinterlacing but I couldn't find anything regarding that. Is there any specific place I might find deinterlacing options?

ATI cards generally have a deinterlacing setting in the their control panel. With 8500GTs being geared a bit for HTPCs, I would have thought there would be a screen somewhere in its control panel, too. My old 7600GT doesn't have one that I see despite a fresh install of new drivers last week, but I swear I read the newer 8500/8600 cards have the option in the driver control panel.

Usually the first tab in gbpvr config you can click on decoder settings and it will bring up a little window of options. (Or right-click on the icon in the taskbar tray if it shows up while playing a file.) If you're using MPV decoder, it for sure has a small window with a deinterlacing option of either Weave or Bob and maybe one other one, I think Auto. I'd set it to off (Weave) for now. It's probably on Auto. Any decoder should have deinterlacing options come up there and let you change them, so you can try the same things with other ones if you want.

I didn't see what you're watching all this on. If you have a non-newer LCD, there's a chance it's just older technology and blurs on motion. That was always a big complaint about LCDs. But, as far as I know, it would do it on motion regardless of the show.

Should be able to check that by playing the video in either VLC or KMplayer, they are both self-contained players so are good ways to get a second opinion on how a file should look. VLC is easier to use for basic options, and you can change its deinterlacing method easily in the menus for testing.

GBPVR does have its own deinterlacing option in the config tabs too, remember. So there should be a window that pops up on the first tab under Video Decoder Settings for the video decoder, and then there's one elsewhere on a tab. I think the gbpvr one is the one I messed with to get rid of my ghosting like this.

There's of course always a chance the problem is caused by something else, but this should be the main possibility.

I seem to have the problem even in VLC. I don't know if it's a recording problem or a playback problem. When I use regular TiVo or watch T.V. without my HTPC I don't have the problem. I disabled the MPV deinterlacer. I couldn't find the GBPVR deinterlacer. Thanks for all the help so far by the way.
