Hi Matt, Based on your Idea I just committed something which will fix your problems using a module parameter. I don't know why Hauppauge has splitted the fix into two, it is not useful, both register-changes are required to solve the issue. By using those settings one will decrease the mobile performance of the receiver, but for fixed-reception it is OK. Can you please try it from my hg repo: http://linuxtv.org/hg/~pb/v4l-dvb/? regards, Patrick.
