I've called support a few times about this and they confirmed that I'm subscribed to HBO but the follwing shows in the log:
19700101-00:00:00 System: reset reason = power on
19700101-00:00:01 CableCARD: M-CARD inserted
19700101-00:00:03 System: network link 1000f
19700101-00:00:04 CableCARD: Motorola card (0000:0625)
19700101-00:00:04 CableCARD: authentication status: authentication in progress
19700101-00:00:04 CableCARD: authentication status: authentication success, activation needed
19700101-00:00:09 System: ip address obtained: 192.168.1.9 / 255.255.255.0
20121107-20:58:28 CableCARD: time changed from Thu Jan 01 00:00:15 1970 to Wed Nov 07 20:58:28 2012
20121107-20:58:31 CableCARD: Tuner0: vchannel 899 (165MHz-670) access = not-subscribed
I can tune all other channels I'm subscribed to in Windows media center, and I have run the digital cable advisor/installed playready. I've called support a few times but it doesn't seem the phone techs are familiar or trained in activating cable cards, and if the logs above is correct I'm still not properly activated.
Thanks for any help!
