So, I just got my Roxio GC HD Pro, (which I didn't order from this website) and I'm getting genuinely mad at this piece of hardware. My situation:
I'm normally plugging my Xbox into my monitor, which doesn't have an HDMI input, only DVI. So my setup is as follows:
Xbox ---HdmiSplitter ---HDMI---> Roxio GC HD Pro
---Hdmi to DVI converter --> Monitor
If anyone suggests checking the cable connection, I'm gonna ragequit and just send this back. That suggestion never helped anyone.
When I start up my Xbox, my monitor doesn't display anything until it eventually lights up for one frame, showing a correctly displayed Xbox dashboard, and then return to showing nothing. It lights up about once every 5 minutes. In the Roxio Game capture HD Pro Software it says "No Signal" while displaying some strange lines which just flicker across the window. (Strangely, those lines cannot be picked up by screencapping, which is why I can't provide screenshots.) Those lines appear to be small parts of a correct image.
I checked my settings but I can't find any property related to the problem.
The Gamecap HD is shown in my Device manager and I already tried uninstalling the device and then repairing the installation. I have tried this both on Windows XP x86 and Windows 7 x64, same results. Might be related to the Xbox as it adjusts to the output (HDMI / DVI), which is pretty pointless, because to my knowledge there's no need for conversion between the two formats.
If you need additional information, just ask. But please don't suggest things like "Make sure you powered on your Xbox". Makes me rage...
