On the tests I did here, they worked, but the Bongani still points that the fixes didn't solve for him. On the tests I did here, the three patches seemed to work [1]. Maybe you could test with those patches and post us some results. There are three patches meant to fix several issues caused by the conversion: http://git.kernel.org/?p=linux/kernel/git/mchehab/v4l-dvb.git;a=commitdiff;h=bdd38d9b5c6365ea004df6d8a183dd1344b4801f http://git.kernel.org/?p=linux/kernel/git/mchehab/v4l-dvb.git;a=commitdiff;h=055a6282cabd311cf010a5a83f0494558504f7d0 http://git.kernel.org/?p=linux/kernel/git/mchehab/v4l-dvb.git;a=commitdiff;h=6e07ff78274752fe812a1e8bddb6013a278e62e8 Could you test please and give us some feedback? [1] Yet, I've discovered recently that the hardware I use for testing PCI devices is broken. Probably, my motherboard chipset is damaged, since I'm getting intermittent bugs on several parts of the machine - even with stable kernels - so my tests with bttv aren't conclusive.
