I have recently connected my pchd 3000 card on my HTPC backend box to my Winegard squareshooter antenna inside my condo. I've gotten some really puzzling results when I scanned for channels. Here is the dumped service list that the card found:

# atscscan /usr/share/dvb/atsc/us-ATSC-center-frequencies-8VSB
...skip the scan output...
dumping lists (15 services)

Done.

I'm having some trouble understanding the output. Discovery, TLC, Lifetime, Starz, Disney, Cartoon network??? From an antenna? Stranger still is that these channels are actually tuneable and I can get the tuner FE to lock on them pretty well:

# azap -r DISC
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 569028615 Hz
video pid 0x0101, audio pid 0x0104
status 00 | signal 3999 | snr cd37 | ber 00000000 | unc 00000000 |
status 1f | signal 28f5 | snr cd37 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal 63d6 | snr cd03 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal 44dc | snr e22b | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal 3a9f | snr eb37 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal ac8a | snr f815 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal ac8a | snr f80f | ber 00000000 | unc 00000000 | FE_HAS_LOCK

Once the tuner is locked on to this signal, if I bust out mplayer I get crc errors in the stream, or mplayer isn't able to find a stream in them at all. Am I actually pulling an encrypted signal off of my neighbor's cable? Any other ideas? Anybody live in downtown dallas that also is able to see these channels OTA?

I've hear dof some Cable operators pushing an 8VSB signal out over the cable lines, but WTF is right, something is boned.
 
I'm stumped. I cron'ed up a script to go out every half hour and scan channels, just to see what I find, but this is just weird.
