Since the 950q support required me to add around 3000 lines to the codebase, I am quite capable of distinguishing the difference between a /dev/video0 device file being created and a product actually working. That sort of attitude might be appropriate when dealing with tech support for a company you just gave money to, but probably isn't the best approach to get help from a group of volunteer developers. Regarding apps that are known to work: tvtime. mplayer. I don't "think" it works. I *know* it works, at least in my environment as well as several dozen other users who have done testing and provided feedback. Since you are comparing against older devices where you believed "every application worked fine", I am sure you are aware that all the applications have issues with audio on raw analog capture devices, and that the way it is dealt with varies by application. Tvtime doesn't support it at all - you have to run tvtime in conjunction with arecord/aplay in a separate window. mplayer allows you to specify the location of the ALSA record device as a command line argument. None of this is specific to newer devices as the apps have the same problems with older devices as well. >> If you have a specific case that is causing you problems, please >> provide details as to exactly which card you are trying to use, which >> distro and application you are using, and what errors you are seeing >> and we will see if we can help you debug your problem.

I just double checked the thread and don't see the lspci output for the ATI card as you suggested. Did you post it on some other thread of discussion? It's probably also worth mentioning that the 950q analog support was added recently (March), so if your distro is too old it will not be in there yet (in which case you won't see the /dev/video0 device at all).
