Allright, sounds reasonable.  Uh.. make it so? =)

Good place for it.  Chris said he'd be probably doing the short recordings 
auto-expire this weekend.

On this topic, the last major things on my todo list before re-enabling 
live-tv:

- software .nuv support (NVR.cpp switching files)
- dirty exit of live-tv (kill the frontend)
- toggle record
- dealing with missing program data.
- deleting needs to modify the tvchain table as appropriate.
and possibly:
- getting rid of the recorder->PauseRecorder() call in TV::PauseLiveTV?  It 
seems extraneous now that it's not pausing most of the NVP threads anymore. 

There's a bunch of other stuff, of course, but everything's mostly minor 
enough to address after it's re-enabled.
