HELP Please! I need some guidance on how to troubleshoot my DVI-D connection between my Comcast DCT-5100 STB and my Infocus 5700.
I have an Infocus SP 5700 projector (DLP) that requires a 1M-DA connector for DVI. [Current Situation] The component and S-Video work fine when connected to the STB at 1080i. My problem is that my DVI-D cable does not show anything on the screen at any resolution 480i/480p/720i/720p/1080i. All of these work with component. Not sure if HDCP handshake error is occuring because nothing is on the screen.
[What I have tried] I have tried connecting to my computers DVI-D port and IT WORKS, but at 1024x768 resolution??
**Admittedly I did not buy the $300 DVI-D to 1M-DA proprietary cable from Infocus.
Instead I bought a 10m DVI-D cable and a 1M-DA converter.
[Thoughts] - I am at a loss of where to start troubleshooting. Since it works with my computer. Maybe that is false positive???
- Is 10M to long of a DVI-D cable?
I even had Comcast switch out the DCT-5100 to a DVR model. The firmware on both boxes was 7.15.
Any ideas or things I should try? Any one else able to get a Infocus 1M-DA connections to work with Comcast STB?

The 7.15 firmware IIRC does not support the HDCP handshake properly. I could be mistaken and it might have been the 7.12 firmware. Sorry but I'm not much help.
