This message is about the Chroma bug in PowerDVD 3.0. If this has been discussed before, let me know.

--------

I don't want to start a fued but our friends sspears and Don Munsil have discovered that version 3.0 of powerDVD has a "chroma bug" while WinDVD doesn't.

http://www.hometheaterhifi.com/volume_8_2/dvd-benchmark-special-report-chroma-bug -4-2001.html

(see the bottom for the list)

It might explain some peoples assertions that WinDVD looks better. I have always used WinDVD but thought the differences were more perception than reality, thinking that both cards outputed the same overlay graphic to the video card. I guess I was wrong.

PowerDVD might need a little tune up to correct the problem. If it already has, please let me know.

Hi Mr. Wiggles:

___I am now wondering this … what if Stacey and Don had used PowerDVD’s capture utility? Would the streaking artifacts have shown up on the captured jpg’s? I am also wondering if SW DVD players via HTPC’s are so good because they not only scale in the digital domain but by all appearances, they can do anything they were designed to do (various sampling algorithms) on the fly. Finally, the upgrade of a SW DVD player is only a download or new video card away (consider BBQ’s find in the WinDVD 2000 ver. 2.6.4 patch from a few months ago or the Radeon swap from the GeForce2’s as an example). As long as the target HTPC or video card has the HP to run the algorithms, HTPC’s can perform wonders for this one artifact that Stacey and Don have posted about in particular.

___I would be interested in Stacey and or Don’s comments on this. I know Don had some serious reservations as far as the HTPC was concerned in his initial Progressive Player shootout. Many of us had given him tips on how to improve on his HTPC experience afterwards because of misconfigured SW and HW and I always wondered if he had used any of the information in the setups of HTPC’s following his initial shootout. Given the artifact shown in the article, I wonder if he has newfound respect for the HTPC in its many forms now? With the WinDVD 2.6.4 patch, the ATI 4.1 player (I would not want him using this for a shootout anyway), and the Radeon of any variant but the “VE†being used as the video card of choice, both Stacey’s and Don’s comments would very appropriate here.

___Thanks again for the heads up on the article.

Mr. Wigggles,

Li On and John K. reported the bug many months back "rat" here in this HTPC forum.

I can definitely say that I saw the chroma bug in PowerDVD on my system. I used chapter 4 of Toy Story to test (same scene as in the Progressive Shootout), and WinDVD looks much better than PowerDVD.
