I thought this wasn't supposed to work...well, it does work! Is it not suposed to work, or am I misconfigured?

How on earth did you get that to work?

Vista or XP?

Powerdvd has no Gamma control, and ignores the driver's "AVIVO" gamma and desktop gamma on XP.

On Vista the drivers don't have a gamma control for AVIVO.

I'm in Vista...Speedy Vista to be exact.

The avivo gamma control works on powerdvd...it just works.

So, I'm the anomoly?

Which Catalyst version?

Vista doesn't doesn't have a AVIVO Gamma control....not in Cat 8:10, so they must have just added it.

Not sure of the version...it was the driver that came with my new motherboard with integrated ATI video. I won't bother updating the driver since it works with gamma now.

1080i at 96Hz is sure sweet though!

Interesting, most of the time I throw the disk that comes with the hardware in the trash and go right to web. It seems like 90% of the time the software that comes with the hardware is buggy crap.

Sounds like you did good though.

Ben, what kind of video files are you playing with powerdvd? I can get it to work as well but not on Bluray or HDDVD media, only on DVD, AVI, mkv, etc...

I haven't played a Blu-Ray yet...I suppose I'm in for a nasty surprise?

I think the stripped down Vista is great...the only thing I miss is defrag...which I'm sure I could hack in there somehow.

As for ATI and gamma...I think I'll beat it!

I'm not even certain, but my driver appears to be 8.522.0.0, does that make sense?

Seems I can also adjust gamma from powerstrip...including individual colors! I suppose I might be able to tame the blue hump by applying a lower blue gamma curve??

I also would imagine that I could load a non-linear gamma ramp...is there something suitable for crt low end gamma correction with powerstrip??

Gamma is not available for ATI cards for BD playback period.

How do I know? My friend is the director of the devleopment team at AMD here in the Toronto area (Markham). His team codes the AVIVO components of the catalyst drivers.

He told me to get a 4xxx series card and try the Dynamic Contrast instead. In addition, the new 4xxx hardware has a new SD DVD scaling chip.

I am begging him everyday to put gamma control in. But it seems there are a number of issues neffoee that will happen if ever from AMD. It seems only CRT users really need this functionality enough, and there are not enogh of us to make a difference.

I work in engineering with developers...I would not necessarily take their word for anything. They can also be wrong...I will prove you wrong when I install the gamma app....and I'll only bother if gamma doesn't work with Blu-Ray. Right now it works with everything I've tried....

Let us know asap. If you try BD. Also, your using the Onboard video as opposed to an external card right? That is interesting as well. Keep us up to date

When you shrink your Blu-Rays...what format are then in? mkv?

Stop using Powerdvd and play with MPC-HC.

The latest SVN build will play BD from disc, and you can use whatever renderer you want, so gamma works fine.

funny you should suggest that...I downloaded it last night. I had an issue with some mkv's showing tearing...which looked just fine on the KMplayer. Man this HTPC biz is hilarious...not one single app, filetype, filter etc works 100% as desired. That being said, I am very impressed with some of the mkv files I have tried. They look and sound very good.

Use the fullscreen mode if you get tearing.

The most reliable thing to do is to convert to MKV and play with MPC or Zoomplayer. That just works. Takes an hour per disc, but you only interact with the PC for 2 minutes.
