Can't you contact the company behind it and recover the registration information?
You could write an auotit script to click that stuff away at start upI have a 60in Visio that is very picky about timing parameters. I am using analog component with an Audio Authority VGA to YpBpR adaptor. This is running an audio meter package program.
I got it to work using the latest version of PowerStrip and tweaking the timing closer to SMPTE specs for 1280x720 TV standards.
Problem is software registration. This system needs to auto start but PowerStrip won't auto-start without registration. It puts up the tip-of-the-day which needs to be closed to start the program. And you cannot disable tip-of-the-day on un-registered downloads.
Is there a way around this. I am willing to pay for the software. And I was also a licensed user back on the 2000s but have long lost that computer and information.
NOTE: Using DVI/HDMI does not help. It does work but still required Powerstrip to tweak the parameters.
