Having the same problem.
PS3 -> Sony TV (via HDMI, HDMI 1 on my TV)
PS3 -> HP RPO (Via component)
HD PRO-> Sony TV (Via HDMI, HDMI 4 on my TV)
HD PRO to PC (Via usb)
On the roxio there are three lights.
1) large roxio symbol
2) HDMI indicator
3) YPPBR (component) indicator
After carefully connecting and checking all cables I commence the PS3 setup.
Form the PS3 sellect Video setup -> Component
Now the next screen in the roxio PS4 stup is to select the supported resolutions (everything except 1080p).
TV goes black.
On Sony TV now select HDMI 4. (Hvae 30 secs to do this otherwise PS3 reverts back to previous video setup on HDMI 1).
Screen black on HDMI 4.
Check HD Pro and the YPBPR indicator has not lit up.
This was a major problem until I discovered you have to start the client software on the PC and manually select the Input to be Component.
This is not mentioned in the PS3 setup but after this everything worked fine.
How ever that was for a while. Now that little work around has stopped working as well.
I know I have changed or messed with the cables (checked again) so what gives. I can now get it to work every 20th time by rebooting again and again and again and making no other software, hardware or cable changes. Do you know how long it takes to boot 20 odd times. I've simply given up using the device.
It is quite clear that the HD PRO does not auto detect the video input between HDMI and component.
I think the only way around this problem is for Roxio to release new firmware for the HD PRO that allows the user to preselect the default video input to force the HD pro to select the necessary video input on power up. So that simply supplying power to the HD PRO will get you a video signal without having the run the client software.
Using the PC client software to select the video input just isn't working.
I hope someone is listening!
