I have the annoying HDCP problem as well. I have an LG HDTV which is HDCP compatible, the 8300HD is directly plugged in via and HDMI to DVI cable (no adaptor). I got my 8300 HD about a month ago. It worked well for about 2 weeks, I was getting the copy protection message maybe once a day, I would push exit and it would go away and would work perfectly.
Then after 2 weeks of working, it just came on full time and would not go away, It says that my TV is not HDCP compliant, to use component...
Funny how it worked for 2 weeks. I called videotron, they we tried simple stuff like reboot, re-flash the firmware etc. They said engineers would look into the issue and they will call me back, been 2 weeks, still doesn't work and no calls.... I called scientific atlanta, they said to ask my provider for the latest firmware, that might fix it (they weren't very helpfull)
I'm using component but I would much rather use the HDMI port, I paid 100 for the cable for a reason...
I've wasted lots of hours reading online, can't find a solution.
I have SARA 18.104.22.168 running. I would love to find a solution.
