cyberham, your numbers are very close to mine, 23 transponders, 268 TV channels (two, including SAT A/V, scan in with 65535 as V and A pids), and 133 radio channels. Naturally, I have 271 TV channels listed, so have an extra three that need to be hunted down and removed, but since I just went through that lengthy process a couple of weeks ago to remove "extras", I will wait a while before I do it again! LOL!
EDIT: The other channel that had scanned in with 65535 for both V and A pids was one of my "extras", so if SAT A/V scans in as a radio channel for you, then our numbers for TV channels matches exactly.
