secure HDCP link not found

I tried the "turn off discovery" option before and it took me 2 weeks to figure out how to use my xbox again because everything was garbled and i didn't have the old OLD OLD tv anymore. Right now I'm using a westinghouse computer monitor and its worked fine
till tonight when I can play fable 3 or download anything including streaming vids for those game ads, but I can't watch a dvd. not a burned copy dvd, an original store bought dvd. what the heck microsoft???

Also there's a number of issues similar reported on the internet. I did a Google search and found them.

Thanks for you help, I'm pretty sure it's not the cable, I have two cables and they both do it on the same TV. I havn't tried it on another HDTV, I'll try the TV downstairs, if this doesn't work then I'll know if it is the TV or the Xbox. Not much I can
do If it is the TV is their, I'll just have to continue using the VGA cable for DVD's and Sky player. Thanks for your help anyway.

Ok so after turning everything off at the power source for 30 minutes, it fixed itself when i turned it back on.. but this was after the third attempt, so hopefully anyone else with this issue finds that this helps also ..

I got the secure hdcp link not found a few months ago.Ive tryed 3 HDMI cables and read everything that i could read about the issue and nothing has helped.I took my monitor to a friends house and used his xbox and movies played fine on it.My blueray on my
monitor works perfect.Its something inside the xbox causing it.I think it has someting to do with the display discovery.I didnt have a problem untill I changed setting out of curiosity one day.
