Question regarding DC10+

A while ago, I noticed that my 6Eyes card had problems when playing back video via the card itself in Fedora 9. I put together another box, containing a Buz, a 6Eyes and a DC10+, running Fedora 9. I found out that the DC10+ shared this inability to play back video, while the Buz did not. Intrigued by this, I set out to find the reason. Step one: Find out when it stopped working. Seven kernel.org kernels were built; 2.6.18 to 2.6.24. In each and every one of them, as well as the F9 2.6.25 kernel, the DC10+ didn't work (neither did the 6Eyes), while the Buz did.

The error is this: When playing back through the card (lavplay -p C), the playback hang and fail with "[lavplay] Error syncing on a buffer: Timer expired" at frame 62 plus four less than the number of mjpeg buffers. That would normally* mean frame 66, with the default -n of 8.

*Occasionally the hang will occur 41 frames later. Why 41? I don't know.

The replay was done with -a 0, to avoid any audio related problems. .18, .19 and .20 were tested in a Fedora Core 6 system, while the others were tested in a Fedora 9 one.

My question to any DC10+ users out there is this: Do your cards behave in the same way, or is there something wrong with my machines?
