Sort of like the old "budget" DVB cards, that had
their own MPEG decoder and video output on them,
except that they would also have their own disk
space for recordings?

Or even outside it, if you are talking about the
MythTV PC having to superimpose OSD, EPG, et c.
It could just be an external FireWire STB, with
the HD video output looped through whatever
special card does the video overlaying.

The other "snags" I see are:

1) Disk space is fixed and finite. Once this CableLabs
DVR "walled garden" fills up, you are either forced to
delete things, or to change the hard disk and start over.

2) Doing the video overlays might be quite hard.
It is possible that the a DVR chip allows write
access to an overlay buffer, but unlikely.

3) What happens if, a few years down the road,
CableLabs changes their mind?
(e.g. DRM cert 5.2 says users are not
       allowed to keep recordings at all)
