HBO & Cinemax June Free Preview

I am glad we have a chance to try these channels this weekend, but there seems to be a problem.  I am setting up my DVR to record some shows, but can only do some of them.  Although I can successfully set up some recordings, others come back with the "Channel is not subscribed" message. Whats really wierd is that I can record the HD version, but not the  SD version.  This has happened to me on CH 408 & 420, while some of the others work OK. (example, Mon 6/11 at 10:15am on CH 408 & Sat 6/9 at 10:00 pm on Ch 420)

Any help would be appreciated.
