Hey All,

I've got an RP56 and a Mits 65819. During bright scenes, I'm getting a lot of noise througout the image. I've tried progressive and non- modes, component video and s-video cables and found the problem lies in both, and have a friend with the exact same tv who doesn't have the problem in the exact same scenes. I'm wondering if I have a bad player, and was hoping to get some input as to others experiences with their Panny. An example of an almost unwatchable scene is Gladiator at 2H19M when they're being lifted up in an elevator to the arena ground level and the camera is looking up at them rising. It's a very bright scene, and there's *pixelation* or *grain* throughout the scene.

Any help on this would be greatly appreciated, as I've tried just about everything I can think of.




My Stuff:

Mits WS-65819

Denon AVR-3802

Panasonic DVD-RP56

Paradigm Performance

Hmm..so I'm not the only one that has noticed this.

I went to Tweeter and testing my Mummy 2 DVD on my RP56 and a Panasonic RP91. Both seems to show that graininess in the beginning scene where Brandon is walking in the crypt with a torch...right before his son startles him.

I haven't seen that scene in Gladiator yet so I'll have to run home and test that part too.

I also tested Mummy 2 on the Sony NS700? and saw the same thing. I suspect it has to do with the way the DVD was recorded.

I didn't notice this on Toy Story 2...but did notice it on Final Fantasy: The Spirits Within.

I adjusted my Gamma and brightness levels again and it still shows up.

ANyone have any answers to this puzzle?

No one else with an RP56 has noticed the graininess?

Dude, I have.

Here's what I think it is though: Older DVDs have this issue because you are watching on a monitor and source combo that displays much more detail than was intended to be seen when the DVD was originally made (i.e. Rob Roy). I have found this problem not to be one and some more recent and well done DVDs like Kiss of the Dragon and Ronin.

So basically, I think it is because the DVDs are grainy, not your player, because I have the same player.

McPatrick is right. On a side note though, you're TV might have it's contrast levels boosted, and that may be the cause of this problem. :D
Even the best transfer DVDs have some grain here and there. You can only hope its minimized and infrequent.

The better your display, the better chance you have of seeing this "digital grain". Proper video adjustments can help reduce it only. Film grain, ha.

MPEG 2 is great but it has limitations and known issues. DVD makers can only hope to keep them from getting out of hand. Widescreen Review did an excellent article about MPEG compression/decompression.

DVDs push the NTSC standard to its limits. HDTV really shows you that. Problem is, against HDTV, that's not enough anymore. Hopefully "HD-DVD" will address the grain issue artifacts (due to compression/decompression techniques) better - along with its higher resolution potential.
Sounds like you're talking about two different things. If you see "grain", that's usually due to the grain in the film. Nothing you can do about that. If the original was shot with grainy film stock, you're going to see grain no matter what DVD player. Unless there's some kind of digital image processing done to hide it during the tansfer process. What I think you all are talking about is digital compression and motion artifact. That's different. I too see a fair abount of artifact with my RP56 that I didn't see with my Pioneer 434, but I can't tell if it's because the RP56 is allowing me to see more detail in the transfer that I couldn't see with the 434? Or, if the RP56 isn't doing such a great job of interpreting the compressed data.

If you're seeing true film grain... that would be a good thing. Means you are seeing the true detail. I've heard people at the movie theater complain that they can see the grain in the film. So, sometimes the projectionist will throw the film slightly out of focus so you can't see the grain. P's me off! I want to see ALL the data. Compression artifact is another animal. Don't want to see that.
