Different DVD decoder picture quality

[dinkob]

I am using imageshack.us if that's ok to link my images don't konw if it's going to work.

This is the first capture of one screenshot. I am trying to find out why is the brightness affected so much when certain connections are being used. The DVD is Underworld and it does not have Macrovision on it.

In this setup it is the polaroid DVD player hooked through my multisystem VCR (which for some reason increases contrast and brightness automatically if the Source and output are the same format (NTSC > NTSC, in other words no conversion through a VCR, just "forwarding" the signal)). The picture quality is OK for watching it through coax. The TV card is hauppage WinTV with VFW drivers.



Now this is the screenshot through RCA which is connected to the Samsung VCR but this time this is the Pinnacle PCTV Pro card that has WDM drivers (same Dvd Player Polaroid 0600 with that DIVX playback).



The next shot is the PROBLEM one. This is the same DVD player connected to the S-Video port of the Pinnacle card using the same brightness settings. Notice how black turns into some sort of blue color and the DVD at this point is not quite watchable.

I am wondering what could be the reason for this? (I was getting the same results through Apex, Cyberhome, KLH player also - the good ones were Philips, Sony and now KOSS - see screenshot below).



Now however when I swtich to KOSS DVD player (I think it's older 2503 model 5 DVD changer that is very buggy operation wise but the picture quality and VCD true chapter playback is what makes it worth it).

the picture is quite pleasant (same settings as above). Note: This is the hauppage card but I think it doesn't matter at this point as we can see from above screenshots that the cards function almost the same.



And these are some questions.

Once again what kind of issue is this?

Why was my brother getting the same problem when he hooked playstation 2 to RCA port of his hauppage card?

Thanks ahead.

Sorry for bumping the thread but would anyone maybe be willing to try the answer?

I am trying to possibly avoid DVD players that have bad picture quality in the future, since the DVD players most likely won't last a lifetime.

Thanks ahead, and I won't bump it anymore.
