Hi Patrick,
did you have time to check the patch I sent recently that fixes the
autosearch for dib3000mc in my case?

http://www.linuxtv.org/pipermail/linux-dvb/2006-October/013907.html

Actually the following one (100% equivalent to the one above) is more
in line with the treatment of seq in the old driver and what happens
in the dib7000 code.

Regards
