DVD HELP NEEDED (real frusterated)


Okay, so I just hooked my samsung hd950 up to my Dell 2005fpw computer monitor via dvi using an hdmi-dvi cable supplied with the dvd player. The samsung screens work fine, but when I put a dvd in, I get a flashing blue and black. I have tried DVI Mode A & B, 420 p, 720p, and 1080i, and I still get a flashing blue. When I put some videos I burned myself (not pirated movies, don't worry, just some trailers and stuff I had in 720p/1080i), they play perfectly fine and they look very nice, probably nicer then playing them off my computer.

What can I do? Is there anything I can do? Must I live with the fact that until I get a tv, my dvd player won't playback dvd's on my computer monitor because of HDCP or something of the sort?

I have an HDMI switch coming that my friend sent out because I thought it'de work (before I encountered this crap.) I was going to hook my monitor (has dvi-d) to the switch using an hdmi-dvi cable, hook my computer to the switch using an hdmi-dvi cable, and my dvd player to the switch using an hdmi cable. Would this make any difference? I am really frusterated at the moment. I thought all this HDCP crap was only for blu-ray and hd-dvd.

HDCP is a headache.

Add a device in between won't solve the problem. The problem is with the HDCP handshaking between your source and HD monitor.

The data stream is encrypted as part of the HDMI protocol. Therefore your monitor needs to be able to decrypt the data stream. It can only do that if its licenced as a HDMI client and it has the necessary software installed to do the decryption.

In theory a licenced device in the middle could be built which does the decryption and then passes a nice clean HD stream to your monitor, however Intel maintains a list of licence codes in the protocol itself. This allows them to blacklist any licence they may revoke.

Intel, upon learning about your device in middle, would simply revoke the licence originally issued to the manufacturer of the device and blacklist that licence in the list of licence codes. Any new media encrypted with the latest licence listing sent to the device could not then be decrypted, which would obviously seriously compromise the usefulness of the setup.

This all works because the distributors of media (eg movies, music, etc) want to stop piracy and they see HDMI as the solution, consequently they will only release their products conformant to that protocol. This means that manufacturers of devices (DVD players, monitors, etc) will want to obtain licence for their products and comply with all the requirements. Intel makes money from the licences.

Everyone is a winner in the process... um except us if we have older equipment which is non HDMI compliant, or if we want to make backups of the data, or if we want to hook up our gear in unpredictable ways, etc.
The other issue is that all this consumes resources, ie: cycles of your CPU and needs drivers and needs support from the OS, etc, which all adds up to extra cost and slower equipment with probable buggy drivers, etc.

And it also consumes power.
A PC playing a HD movie with copy protection (encryption) is consuming over 30% more power than a PC playing a HD-movie without copy-protection (encryption).
