Pinnacle Dazzle DVC 100 doesn't stream live video

I'm trying to stream video on websites like livestream.com using the Pinnacle Dazzle DVC 100 external capture card. To connect to the TV, I use three A/V splitters for the two audio and video jacks in the DVC. In each respective splitter, I connect both the component from a game console and an A/V cable, and the A/V cable runs to the television.

When I preview this in a program like Cheese, it works flawlessly, the video is perfectly in-sync with the television. When I try to connect through the livestream studio however, the video flickers on for a split second, and then disappears. The audio streams perfectly (after the recording source has been set to the DVC 100 in padevchooser). This is interesting because the exact opposite occurs in Windows. In Windows, the DVC can stream video, but has trouble streaming audio. If we could get the video working properly, that would be one more leg-up on windows, especially in the streaming and video/multimedia community.

I used sudo rmmod uvcvideo to remove my laptop's internal webcam to avoid having the video sources competing with eachother (I thought that might have been what was causing the video fail in livestream).

Here is the output of dmesg|grep video
[ 0.600407] pci 0000:01:00.0: Boot video device

As you can see, it detects the webcam, the DVC 100, and then I disabled the webcam.

Here is the output of lsmod|grep video

There is no additional dmesg when the stream fails on livestream.

Another potential cause is the fact that livestream is flash-based, and flash may have trouble getting the video information from the DVC 100 driver.

Running Ubuntu 9.10 Karmic, with Kernel Linux 2.6.31-16-generic

Is this worth filing a bug report as it could be a bug in the DVC 100 driver (seeing as the video works fine in the Windows driver)?
