Why do I see artifacts when I'm watching a DVD?

[50]

Okay I don't know which forum this belongs in but oh well. Okay I don't know what a DVD is supposed to look like on a computer, but is it supposed to have blocks of color and artifacts when watching in full screen? Do we not see these artifacts when watching it on TV because we're so far away from the TV? Could it be that my LCD lags so it creates artifacts? On powerdvd this is what it says

Do the settings look wrong or is there something wrong?

No, you shouldn't be seeing artifacts. A few things:
1. Try different DVDs, make sure it isn't just one in your collection causing the artifacts.
2. Update your video drivers.
3. Try different players. There are some freeware/ shareware ones out there that you can download and try.
4. Make sure you're using the latest DirectX.

Just some suggestions.

Well I see occasional artifacts when watching a DVD on my home surround system. Combo DVD/Receiver/Amp, not my PC.
It usually happens several times while watching a movie.
I'll get a couple of quick blocks of color, then they are gone. Only a second or two.

Did all that, except #3, I thought PowerDVD was the best player out there?

Well, that's kind of subjective. It could be that PowerDVD has some weird compatibility issue with your particular video card/ DVD drive or something. To be thorough, I'd try at least one other player. If that doesn't fix the problem, try calling tech support for your video card.

If I take a screen shot and post it on the web, will it show the artifacts that I see?

You might also have a POS DVD drive. I had a Delta drive and it caused the exact problem you are describing. I picked up a Pioneer DVD drive and the problem was solved.

If you do a screen capture while you are seeing the artifacts, you should see these in the capture as well.

> If I take a screen shot and post it on the web, will it show the artifacts that I see?

A regular screenshot won't. Try a utility like HyperSnapDX.
EDIT: Things like DVDs, AVIs, or TV tuner video can't be captured in normal screenshots (i.e., PrtScrn). You need a special utility to do it.

i hope this link works
here's another screenshot

It's a sony DVD drive(I don't think it's a POS) model DDU1621

I just checked your screen shots. My blocks of color were about 100 times worse than that. Probably not a POS drive, besides Sony is a good name.

One of the most overlooked problems is a dirty disc/dirty drive. Make sure the DVD disc itself is free from dust and finger print smudges. The DVD drive should be regularly cleaned with a cleaning disc (readily available from Walmart to CompUSA). The majority of artifacts I've had are from dirty discs.

Another is the software player/hardware combo. I've used PowerDVD and WinDVD, and WinDVD has the better picture quality. If you have a slow system and/or a video card that just doesn't cut it for DVD playback, you'll have problems as well. But looking at your hardware, I don't see this as a problem.

Are you using a standard resolution? Forcing Fullscreen of a Widescreen dvd?

 

[bacillus]

I'm only guessing here but I suspect that you're using powerdvd 5 as I've seen other folk complain of the same problems.
you will find that powerdvd xp aka version 4 works flawlessly!

 

[0roo0roo]

hard to tell. some dvds are better encoded or have higher bitrate then others. some like starwars the phantom menace look like sh*t with tons of edge enahcenement halos etc. others are superbit with or without labeling and are simply crystal clear. major artifact i see is the full screen aspect ratio


try a different dvd, perhaps superbit.

bigger your screen, the more obvious any dvd artifacts are. its not hdtv resolution after all

Are you really watching a DVD or are you talking about a DVD to SVCD? If it wasnt encoding right you'll get artifacts.

 

[50]

hey, thanks for the replies

Are you using a standard resolution? Forcing Fullscreen of a Widescreen dvd?

I don't really know what you mean, I play all of my DVD's in fullscreen, I keep the aspect ratio. This is probably a dumb question but does making the screen full cause artifacts? I can't imagine people watching their dvd's in a window 3/4 the size of the screen

I'm only guessing here but I suspect that you're using powerdvd 5 as I've seen other folk complain of the same problems.

I've tried both, that screenshot is from Powerdvd 4

Are you really watching a DVD or are you talking about a DVD to SVCD? If it wasnt encoding right you'll get artifacts.

It's an original DVD...

 

[sandorski]

Well, if it is a Widescreen DVD, then forcing it to Fullscreen will cause distortions(it gets compressed and stretched). If it is a Widescreen DVD, try watching it in Widescreen and see if the distortions still exist.

the screenshots were from the letterbox(4:3 ratio) dvd

 

[sandorski]

hmm, I'm stumped then.

 

[Mday]

i think the source was f'd up. they probably boffed up the encoding job.

Well, he was watching the 4:3 ratio DVD. :vomit; That's b0rked up enough as it is.
