BTV with Vista: Deinterlacing problems

[John Sparks]

ok, I have a rear projection crt HDTV that I use as my secondary monitor to watch beyond tv on. It automatically deinterlaced tv signals.

When I watch BTV recorded MPEG shows on my tv, (standard def tv show, playback settings: deinterlace off) whenever something moves, I see interlace glitches along the edge of the object, you know scan lines. Its very aggravating.

So I turn on hardware deinterlacing in BTV and when I watch the show it scanline problems are gone but the picture looks all "smeary" and blurry. and when object move quickly instead of scan lines I get what look like ghost outlines trailing the object Like O)))

When I watch the same recording in Media Center, it looks fine.

I actually had the same problem in XP, but I changed the playback codec from the snapstream one to Intervideo (which I had on my system) and it fixed the problem. I could watch my shows with deinterlacing turned off in btv and they would look fine.

But now under Vista, no matter what codec I try I get the same problem. The intervideo codec doesnt help. Or it may be the upgrade to BTV 4.7 (I had 4.6 on the machine when it had xp on it)

I also tried fiddling with the graphic card setting (ati radeon 1800xl) but nothing made a difference there either.

Anyone have any ideas? Or know of a way to use the media center mpeg decoder in btv? because the videos look great in media center. I would just watch them all in there except it has no commercial skip.

Right now my only recourse is to showsqueeze everything. If I showsqueeze to divx or wmv, it deinterlaces the video and the playback looks fine. Its just real time consuming.

Vista bad. Vista very bad.

Seriously, I've had no luck with it and BTV. I don't consider it a BTV problem, just a new, unstable OS.

actually I have had no problems with vista or btv under vista other than this one. It seems more stable than xp was, I was having all sorts of crashes under xp, thats why I finally gave in and installed vista.

ok I think I may have found a solution myself. I am still testing it.

I downloaded the K-Lite Mpeg codec pack:

and installed the various codecs. you can only install one at a time so it took a lot of messing with.

I finally tried the Intervideo Codec. after you choose it, it asks if you want to install the hardware acceleration or not (check box) - first I said yes, and everything looked the same, interlace artifacts. then I uninstalled it and reinstalled it withOUT the hardware accel.

Everything looks great now. I don't have the hardware deinterlacing turned on in btv playback settings and I have no motion artifacts.

My current settings under play back:

Intervideo Video Decoder [no hardware accel]
Snapstream Audio decoder
3D accelerated
NONE for Deinterlacing

Unless I post back here with bad new, everything seems to be working fine (just did it about 15 min ago so I am still crossing my fingers. )

just reporting back that the solution I found is still working. Looks like this might be a solution to a lot of the deinterlacing problems I saw others having when I searched the forum.
