Why can't you get great DVD quality when watching a dvd on your PC? It always seem kinda lacking when you compare it to the quality on the TV.
 
crap upscaling...

Yup....

your moniter?

Bingo. But no not because the monitor is carp.

Doubt it... LG 22" wide with 3ms response time.

The size just makes it worse. Dvd looks good on TV for a couple of reasons. Normal TV's are low def devices, so low def content looks ok. Secondly, with your LG, the screen is meter or less away from you. This means you see every little imperfection, upscaled. With TV, you are normally at least 3 meters away, so you notice farr less imperfections. Start moving away from the screen, and it starts looking ok. Sit as far away from the screen as you would when watching a 54cm TV, and it looks almost perfect :p
 
DVD quality is just rubbish compared to what a LCD screen can show.

go and sit the same distance from your TV and you can compare them properly.

720P and 1080P looks great on LCD screen.
 
If you're comparing CRT monitor to CRT TV, then another reason is that TVs use a phosphor with much higher persistence than do computer CRT monitors. This makes motion sequences appear to 'blend' better.
 
Cause your pc resolution is a lot higher than your tv. Unless you're running 640x480 on your pc, in which case you're probably sitting too close to your screen.
 
You may need to fine tune the contrast, brightness and gamma settings too.
These settings may be off for the video overlay layer. This layer uses different settings to the usual settings used to display the windows, menus and other graphics on your PC.

I also found that when I use media player classic the dvd looks ok...

Using dvd player programs (power dvd) it use to look terrible using my on-board gfx.

Now with my 3850 and dvi connector to my 19" lcd, it looks crisp... :D

So maybe software opposed to hardware playback differs?

I could be wrong though, didnt research much coz I dont watch that much dvds
 
Perhaps starting at what resolution a DVD originally is, is a good starting point. Then we have to consider that A LOT of re-coding (and whatever codex do) has to happen a few times a second... So, frames may be dropped, and resolution decreased to make streaming faster?

...just a theory. Will research it some other time.

720 by 576 if PAL.
720 by 480 if NTSC.

So view DVD in that size (native) and not full screen, adjust your video overlay contrast and saturation and optimise your screens contrast as much
as possible. Try to disable deinterlacers, as the 'dumb' deinterlacers remove
50% of the information present in your MPEG2 stream.

And I'm assuming that Blue-Ray is a lot better resolution? :D
...I'm telling you, the things we learn on here. So much better than Google.

Bluray is 1920by1080.

However the aim of Bluray is to project that image over a huge area and to in effect get the same amount of detail as SD PAL DVD but over an area 4 times the size. :) The magic of HD isn't about staring at a PC screen from 30cm away and seeing pores on some actors face. I guess you could use it for that, but the real deal is Home Theatre - ie see the detail you see at NuMetro at your home on a screen say 72 inches across.

LOL!!!! :D

Some day when I grow up... I'll own one of those. Hmmmm.....Home theater...Going to the movies in your boxers without being arrested. Sounds like the dream.

Eish, someone suffers from extended underpants radius.

Anyway you sure the DVD wasn't perhaps of err... the less legal kind? Because those things are just low-budget, plain and simple, proper DVD's look ok to me on a 22", it's not the same as hi-def that's for sure but not exactly horrific to watch.

Nope... I don't buy Illegal stuff. :) It's legal DVD's. And, well...keep in mind I'm about 60cm from my 22" Wide screen...
*Remembering all the times mom yelled that we must sit far away from the tv...*

Yup, don't look at those JAV VCDs or you may go blind.
