Ah, I believe this may have been caused by a very recent changeset: http://linuxtv.org/hg/v4l-dvb/rev/ad6fb7fe6240 I tested all of my changes thoroughly, and had received positive test results from other users with various hardware. The regression was not part of my tuner refactoring changes, and I do not think that this is upstream in 2.6.25-rc. Can you confirm whether or not the above is the problem changeset?
