Turn off antialiasing stops skipping?

[Deusxmachina]

Surprisingly, "antialiasing" only brings up five or so threads.

Overlay is an angel, and VMR9 is the spawn of satan. Having said that...

I had CCCP codec pack and Powerdvd 7 on my computer and that's it for codecs. The only way I got Live TV to work is using MPV codec for video, although the Cyberlink codecs worked for audio. I was getting a skip, and then did the quartz.dll mod and maybe a couple other things that didn't help.

I then opened up PowerDVD and turned off the "smart deinterlacing" box that was checked. I would have thought that wouldn't make any difference since I wasn't actually using Powerdvd to watch video, but instantly the skip went mostly away. With deinterlacing set to auto on my ATI 2400, I guess it was double-deinterlacing and something didn't like that -- although I wasn't using the Cyberlink video codec.

I left live TV on overnight and woke up to GBPVR locked and the computer's memory maxed out, like it's a memory leak. I had also noticed the longer Live TV was on the more the skip came back and would get worse. Rebooted the computer and the skip was still there again even though PowerDVD was now uninstalled (using MPV for video and FFDshow for audio).

All that leads up to this: do people have all the video card control preferences set to off or set to "controlled by application"? I had/have ATI deinterlacing on, 3:2 pulldown detect on, mipmap on high, etc. I was getting the bad skip again today, and I turned off antialiasing in the Catalyst control panel, and the skipping went away immediately without rebooting and it's been fine for the last hour. I was hearing my hard drive "skip" a bit with the video before, too, whereas now it's silent.

I have football on right now and if having AA off made the picture worse I certainly don't notice it. The picture still has a couple annoyances, motion is a little blurry (probably a deinterlacing setting problem), and every 30 or so seconds a "wrinkle" or "fold" makes it's way down the screen (wrong refresh rate?), but I can live with that for now.

Having the card's antialiasing off hopefully fixing the skipping threw me for a loop, so if nothing else I wanted to make other people aware of the possible fix.

the antialiasing can do funny things so turning it wont hurt (its picture smoothing crap for games not really needed if you ask me for mpeg playback)
so is the Anisotropic i turn that off aswell more picture sharpening crap same again try it turned off
these are both things that interfere with the picture in strange ways that you really have no control over

vertical sync(set it to always on) should stop that line going down your screen if its the one i think it is
your output refresh rate should be 60hz (yes i know you are going to say but it will look like crap with a low refresh rate well sorry mpeg ntsc is 30fps so it has to be in multiples of 30 to get smooth paning shots)

The refresh has been 60hz the whole time since I knew that would rock the boat the least. The wrinkle line scrolling down from top to bottom was very obvious on live football earlier, happening every 20 or 30 seconds, but right now there's only filmed shows on and it's harder to notice, so maybe the type of broadcast or fps affects it. Locking the vertical sync may have lessened it, but it's still there, but it's also a relatively minor thing.

I set the Anisotropic to "set by application" like with antialiasing and whatever else is in there. I'm still surprised that cleared up the skipping. Was amusing reading some threads elsewhere of people talking about their Tivo problems, reminded me the grass isn't always greener on the other side.

And now, GBPVR has been on all day, I set it to record some shows and it did, and now it's playing them back. Looks like the main stuff is working well. Victory is Mine!
