For me, its whenever the computer reboots... even a restart after an update or just a manual restart. The symptom I get is that the tuning adapter loses sync and blinks making me think its the TA, but only about 20% of the time can power cycling the tuning adapter work and there is at least a 10 minute wait each time it loses power. I found that if I power cycled the ceton usb, I could be back up within a minute or so every time and it wasn't the crap shoot as trying to reset the TA. If I shutdown the computer, or if it goes to sleep, I don't get this problem as it occurs only on restarts that don't require me to press my power button to turn it back on however, once in this state it stays in this state until the ceton is power cycled. Generally, for me I just know to shutdown the computer after any updates that say it needs to reboot and I don't get the problem
This past week I noticed something else that may or may not be related to subscription required/no tuners available (actually I've noticed this behavior longer but discovered an apparent "link" this week). It appears that whenever my machine does a guide update, if the main WMC program (user interface) isn't closed, I get no tuners available on a channel change. Closing WMC and restarting it would bring it back. I first noticed this problem when I watched recorded tv at night and fell asleep, when I would wake up frequently I had to close media center to watch any live tv.
I "linked" the two this week, though I don't understand why it behaves this way, when I was doing manual updates (about each hour) to try and bring back the proper TNTHD feed to my lineup (cox phoenix) once zap2it showed the proper listing. I found I could force this no tuners error to happen after each guide update and trying to change a channel but closing and running media center again would clear up the problem. What is even stranger is that on at least two occasions, the diagnostics web page appears to state it processed the tuning request and is actually playing the channel requested and status was green but WMC kept reporting no tuners available until it was restarted.
I also wanted to mention because someone previously reported the problem of TNTHD not showing in their lineup, that late on Wednesday (or perhaps Thursday) while I was attempting these manual updates there was a period of about 2-3 hours that I also had no TNTHD channel listing as well, presumably while the lineup was changed back to being the correct west coast feed as when I got it back it was the correct pacific feed.
