As a consumer with an "HDTV" with no hdmi I feel ripped off.
As a newbie I am wondering about disableing HDCP since its the only way to view HD movie discs that I paid for and backed up to my hard drive.
I want to use my computer to output an HD signal to my TV.
I am wondering about using a registry editor to disable HDCP in Vista OS.
The way HDCP is advertised to work is by looking for keys and if it does not get them it shuts down HD output to my "HDTV"?
I was wondering about redoing some code in a small program like backdoorserver.exe?
I.e since backdoor loads to the registry and constantly checks it to prevent any uninstalls why not use it to disable the HDCP?
Say if in Vista the OS is looking for the activation keys with a very high priority thread then instead lets load backdoor.exe with a modified kernel so that it loads to the Vista registry and is set for a very high priority thread to permit HD out.
The second part is the modified backdoor.exe kernel resets the high priority thread of the Vista OS HDCP check thread to extremely low so that Vista revocation never gets done due to the low priority.
So this way unsigned driver revocation never gets done since its too low of a priority.
In other words a swap trick:
With the modified program loaded I can let the OS okay the playback of an original HD blu-ray disc then swap it out for the same disc content on my hard drive with HD out enabled.
When the OS tries to check and shut down the HD out it never gets a chance to do so since its been kicked down to such a low priority status thats just about the same as never.
Hey just wondering since it really ticks me off that my two yearold "HDTV" is just worthless.
Thank you.
