This was an option added to the SFE driver which has now
become obsolete. A new patch for this can be created easily
enough though. The i2c errors you are probably reporting
here have also been fixed in MFE (see below).

I put this is the patch also. Radio doesn't work though. There is
not enough information as to how to fix it as yet.

The above has been reverted for the hvr-3000.

I am about to prepare a new patch-set for the above but in the meantime
you can look at this:
http://dev.kewl.org/hauppauge/gate_control-8894.diff
This fixes some loading time i2c errors and also errors with
moving from DVB-T to analogue TV.
Other errors found which occur when moving from DVB-S to DVB-T
are work in progress and will be fixed later.
