Hmm... I suspect that there's something wrong with those changes.
Testing it with a dib8076 usb stick seems that the code is worse than
before, as it is now harder to get a lock here.
With the previous code:
INFO Scanning frequency #1 725142857
Carrier(0x03) Signal= 67.46% C/N= 0.00% UCB= 0 postBER= 0
Viterbi(0x05) Signal= 67.08% C/N= 0.00% UCB= 0 postBER= 2097151
Viterbi(0x07) Signal= 67.54% C/N= 0.25% UCB= 165 postBER= 0
Sync (0x0f) Signal= 67.06% C/N= 0.23% UCB= 151 postBER= 0
Lock (0x1f) Signal= 67.58% C/N= 0.24% UCB= 160 postBER= 338688
Service #0 (60320) BAND HD channel 57.1.0
Service #1 (60345) BAND 1SEG channel 57.1.1
With the new code:

So, it seems that the changes broke something.
