Does anybody know if you can actually play Copied DVD's through HDMI that adheres to HDCP?

What do you mean by copied DVDs? The DVD will either have copy protection or not. If the matirial is copy proected it must be transmitted through HDMI/DVI-HDCP if upconverted.

If the matirial isn't copy protected then the component video connections as well as the HDMI/DVI connections can be used for upconvertion.

I mean when you backup a DVD by using one of the known copy programs, is the encyrption still present on the backup DVD because I thought that the copy programs along with AnyDVD strips the encryption from the DVD thus alowing you to backup the DVD. What I'm trying to say is that, if you backup one of your DVD's that you own, using let's say 1click DVD with AnyDVD, can you play that Backup DVD into your DVD player that has a HDMI output to your HDMI input HDTV?

What I'm trying to say is that it doesn't matter. That isn't how HDCP works. HDCP doesn't prohibit the playback of copyrighted matirial. HDCP will only prohibit the use of the upconversion feature if the DVD is copy protected and the display device isn't HDCP compatible. Although 480p is still achievable via component video.

Yes, all copy protections are stripped when a back-up of a DVD is made (assuming that it isn't a DVD clone/Image burn proccess).

I think what he's asking (and what I'd like to know) is: Does HDCP prohibit upscaled playback of copied DVDs that have had the copy protection removed?

Thanks!

No.

When copy protection is defeated there isn't anything that states that the copy protection has been protected. The player doesn't know that the disc is made from matirial that was previously protected and so treats it like any other DVD that doesn't have copy protection (ie. home movies).

Unprotected is unprotected. Thats the real reason there won't be any high-def movies deliverd via the DVD format even though the DVD format is more than capable of holding a HD movie with extra featers.
