Comment:

 (In [9349]) Closes #1502. Adds a workaround for broken DVB drivers
 recommended by DVB guy Manu Abraham.

 Basically, this adds a user specified hard delay after telling the driver
 what transport to tune to, but before we ask if it has finished tuning
 yet. This defaults to off, and is configurable in mythtv-setup's
 "Recording Options" pane for a DVB card.

 If we detect a frontend name of "DiBcom 3000P/M-C DVB-T" when initially
 setting up a DVB card, we auto-magically set this delay to two seconds.

 "DiBcom 3000P/M-C DVB-T" corresponds to a revision of the Hauppauge Nova-T
 with currently broken Linux DVB drivers. Kenneth Aafloy previously
 reported that this would be fixed in the 2.6.12 release of Linux, but
 since it hasn't been fixed yet and we are at 2.6.15.6 now I presuming that
 fixing the tuning bug for this card has a very low priority for the DVB
 driver folks.
