(For example, have you fixed the issue that causes a kernel panic when recording analog video with MythTV? That was a particularly interesting one.) In any case, that's another issue entirely - this code is for DVB-T support. Also, just because this device isn't being sold anymore doesn't mean it's not worth adding - there are other, fairly similar devices still on sale. Unfortunately, I don't have access to newer hardware, and most of the people with the access and knowledge don't seem to want to have anything to do with it. (Why do I have a feeling that you have a hand in this?) However, adding support should be easy - all the necessary code exists and has done for a while (even drx397xd support for the Pinnacle 330e and the new HVR-900). Mainly, though, I'm doing it for my own benefit - I have this hardware, and the changes are small and self-contained enough that I should be able to stay up-to-date with upstream and keep newer kernels working with minimal effort. (This tree is actually an updated version of code I've been using for the past few months on PAL-I and DVB-T, but didn't publish due to a bug with switching from digital to analog.) (By the way, I still reckon your userspace code is a dead end, at least as far as getting anything merged into the kernel. I think I may have already explained why.)
