Hi

When I am using the build in decoder for my dvb-c reception, deinterlacing is great but there is alot of ghosting/smearing going on on various channels. Same with some DVD´s...

Progressive signals are all good.

If I switch to PowerDVD 7.3 the ghosting/smearing is gone, but deinterlacing is hell...

What to do... it´s so annoying....

Vista Ultimate

Ati X1600Pro

Catalyst 7.5, Deinterlacing is set to Auto.

All updates from MS

i think we're all going to have to wait for more mature decoders & graphics drivers

I have an ATI X1300 and have seen the same ghosting/smearing issue.

By changing the ATI deinterlace options from auto to Bob and rebooting the smearing issue goes away.

I am using the MS DVD codec

I had the same issue, and as buellpilot says, switching the de-interlacing from auto to Bob fixed the problem.  I'm using an X1650 and the MS decoder.

I'm looking to build a VMC rig soon, and obviously decode quality is an issue for me. So I've got to ask, what do you mean by "smearing" ...because I tend to picture that as bad de-interlacing.

And if so, in what way is PowerDVD interlacing bad, but not smearing? Do you mean there are lots of comb-lines and the de-int doesnt seem to work at all?

That is your problem. The ATI cards have excessive noise reduction that causes a bizzare "ghosting" or "afterimage" effect, particularly on digital content. If you turn down the deinterlacing you can get rid of it but you will then not get the nice adaptive deinterlace.

ATI is aware of the issue, I have no ETA as to when they will provide a solution.

This is not an issue with the decoder.

You may want to consider the NVIIDA 8600GT, running the 158.18 drivers.

Hi

Thanks for all the replys, changing deinterlacing to BOB is not something I fancy (throwing away every other line)

So I have searched and searched the web, and then I stubled upon this...

setting DI_METHOD (deinterlace method) to "1" solves the ghosting problem when using the x1000 series mpeg2 hw acceleration under windows Vista...

You can accomplish this using Ati Tray Tools, I just tried it last night and it seemed to help, and deinterlacing is set to auto. Will do some more extensive testing of different sources later.

But I was watching a DVB channel which had horrible ghosting and after setting the tweak it dissapppeared.

I just tried the DI_METHOD on my x1650 and it may have reduced the ghosting, but it made the rest of the picture terrible.

Is your signal mpeg2 ?

All video in MC is MPEG2. This issue just looks much worse on digital feeds in general.

Setting the deinterlace mode to 1 is almost as bad as bob. I don't think it is bob, but I do think it is ATIs oldest adaptive deinterlace.

I try not to pimp one hardware guy over the other but right now, at this moment in time, NVidia has the upper hand as far as video on Media Center goes. I'm running an 8600 at home and it's been rock solid with none of the funky artifacts currently seen with ATI parts.

Just my $0.02 worth. I change video cards like some people change clothes. It all comes down to what your time and annoyance is worth.

Great - I spent months trying to get nVidia to work, and like 2 weeks after i give up and buy ATI, they released a beta driver that seems half decent. Mind you, having to have an 8x00 card just to run video is ridiculous, when my old Matrox Millenium seemed to do an OK job that that probably had 1/100th of the power of a 6600.

And yes, i have DVB-T, so the ATI smearing is shocking.

You are right the picture became shite...

Then I tried something different, with ati tray tools I have now set denoise to enable and in CCC deinterlacing to vectoradaptive.. This seems to give me a sharp picture with no ghosting.

Even bob gave me ghosting ... arrgh darn drivers...

Where is this set in the ATI tray tools?

Thanks.

Hi

The newest ATT has a "Vista AVIVO" entry in the pulldown list.

There you can enable denoise among others...

Too fast on that one.. still smearing.. peoples faces move independently .. scary..
