How Can I make 1080i Television look better?

[craigap]

I have a 790GX mobo (ATI HD 3300), and 1080i television looks like crap. I get tons of flickering lines all throughout the screen when the camera that recorded the show is moving. 720p seems fine. I'm guessing this has something to do with deinterlacing, but I'm not sure. I'm using a trial of PDVD 9 which seems to allow me to use the codec indefinitely, however it won't let me play dvd's after the expiration. But playing TV recordings in WMP it says it's using PDVD 9, so I guess it's working. I have also tried AVIVO, but that doesn't do any good either. Also, if I use AVIVO my CPU usage goes up (using EVR), so it appears I don't get the same Hardware Acceleration from it.

I got the same problem man....it looks decent for awhile watching 1080i show then green and pink flashes across the screen show up. Watching football looks grotesque at 1080i. I also have the ATI HD 3300, excep twith COreAVC codec. Help is appreciated.

Just setup your STB to 720p.
I too hate interlaced material.
Watch ABC or FOX. They are 720p channels. If you feel the same about those channels you should change your video card/PC.
Or just buy a HD200
By the way... FOOTBALL is supposed to be watched in 1080i.

I don't know if this applies to your HD 3300, but I had a problem with 1080i content with an ATI Radeon 2400 HD Pro and solved it using the instructions mentioned here:

I got OTA channels....i think football should be watched in whichever format gives the best playback...you dont agree?

That link won't help me out, but thanks anyway.

I don't use an STB either.

Have you tried different video renderer settings in Sage?

If using VMR-9, try switching to Overlay. If using Overlay, try switching to VMR-9. If you are using Vista or Win7, try EVR instead of VMR-9 or Overlay.

Also, if using VMR-9, try enabling FSE (Full Screen Exclusive Mode).

When changing the renderer and/or enabling FSE, you may need to re-start the SageTV UI to make them take effect.

[craigap]

I've tried every combination of FSE, VMR, EVR, Overlay possible and none of it really matters. At times it seems switching to overlay helps some, but not good enough.

Just to add: I am using Vista Business for the OS.

Kind of sounds like a Deinterlacing problem. IIRC the 780G (Radeon 3200) needed an AM2+ CPU to enable the advanced deinterlacing features.

[craigap]

In the CCC I have the deinterlace method set to Vector Adaptive which I understand to be the best available. Is this what you are referring to?

[stanger89]

Yeah, and I suppose if it let you pick that, it's available and you've got the right processor for it.

[craigap]

I popped in an HD 4350 and it looks perfect now. Maybe there just isn't enough power to run vector adaptive deinterlacing even though it allows me to check. I too recall at some point in the past where I read about the need for the increased hypertransport bus that comes with AM3 CPU's. I tried the other deinterlacing options, but none of the others seemed to make a difference either.

Which CCC version are you using? I have 9.9 and have it set to just adaptive. With cyberlink h.264 codec i have it to where only in very fast camera panning do i get some "jaggies," i think the term for it is.

You dont think your onboard graphics card is good enough for it?

Did you force the VA setting (via vforcedeint)? I'm pretty sure you cannot get VA for 1080i with a 4850e processor.
I used to play with these options previously (and I also had the same processor for a short time), but ended up not using VA, since it doesn't work for 1080i with this kind of hardware.
Otherwise a 3300 (or 3200) is perfectly capable of playing 1080i.

I just recently updated my drivers to 9.9 so I have that CCC.

I will so No to that first question, because I don't know what it is. All I know is that if I uncheck the automatic box it will let me choice what eve deinterlace mode I want. I've tried them all. If I leave it in auto it still sucks. I decided it was either try one of the new 45w tricores coming out or a hd4350. I went with the latter and it works a lot better. Occasionally, I do get a cm thick distorted looking band that spans the top area of the screen horizontally. I got this same band with the onboard as well, but just a bit thinner.

So you still dont think your onboard graphics are good enough....the HD4350 is a graphics card right? Sorry to be repetitive I just want to punch my computer whenever the playback gets jittery, anxiety sets in, i start getting dreaded thoughts of TIVO.

Rather than having dreaded thoughs of a TIVO, you should be having pleasant thoughts of an HD200 Extender

I'm not going to say the onboard graphics isn't powerful enough. That probably isn't the issue. The issue that I'm leaning toward is something with deinterlace modes and codecs. I haven't bothered to try other codec options other than PDVD 9 and AVIVO. Maybe what I lack in a good deinterlacing mode and codec the ATI HD 4350 makes up for with a little more horsepower. Hard to say for certain without a lot more testing that, frankly, I don't have the time for.
