If you look back to earlier in this thread, I gave an explanation of the testing that I have done last weekend. Using 2.6.22, the initial tuning params work properly and all attempts afterwards do not. Regardless, things are now beginning to make sense, although I do not understand why the latest HG works fine with that card for me against eariler kernel revisions. Perhaps I made a mistake in one of my tests. Now I know exactly what needs testing. How to fix this cleanly, that I am still not sure of, without affecting other drivers. Maybe we'll have to hack the flexcop i2c handling to fake a good i2c reply. I'll look into it when I get back home. -Mike _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
