I recently ordered a triple play Time Warner bundle and got a Motorola DCX HD DVR for the living room. Considering I also have a PS3 I decided to get a 3-to-1 HDMI switch from amazon since my tv only has one HDMI port.
I can't post link to amazon due to 3 posts rule but it is the "Ultra High Performance HDMI Switcher, 3to1 Switch" by Portta.
I hooked everything up as follows (all using HDMI cables): DVR to switch input 1, PS3 to switch input 2, and switch output to tv. The switch does its job, it auto switches to the device it "sees" a voltage from. However I get about a split second of video and then black screen, I still get sound though.
After a while, repeated turning on-off it started working, I finally got video. Went away and then came back an hour later and once again I was getting no video and only audio. From everything I've read this has to be a handshake issue. So any insight into how to go about making it work would be really appreciated. ty
Switches and cable boxes have been a problem occasionally. However, there are a few things to try. First of all, set all devices (PS3 and Mot) to 1080i as a test. Also make sure that the Deep Color option on the PS3 is set to "Off". Deep Color provides no useful function at this time and eats-up HDMI bandwidth. You might also check your TV and the Mot for Deep Color and set those to "off", although I don't think the Mot has that option.
Now that you've lowered your HDMI bandwidth, test again and see if that works. If it works, then you might check the pedigree of your HDMI cables. One or more may not be up to the faster speeds.
If that doesn't work, it is probably an EDID handshake issue or just bit errors. I would not expect an HDCP problem to allow you a second of video and then no picture but still audio. HDCP is designed to allow nothing until the link is authenticated.
Also, for further trouble-shooting, there is an HDMI section of the AVSForum near the bottom of the forum lists.
