Interesting, although I'm slightly confused.

My patch mere added the ability for dvb-core to tri-state the tsport
out bus, similar to other digital demodulator drivers in the tree....
and testing with both azap and tzap (and dvbtraffic) showed no tuning,
lock or other issues.

What happens if you tzap/czap a known good frequency, before and after
my patch, without your sed replacement, leaving T/T2 and A fully
enabled?
