can Media Center record any program that already started?

media center already has 30 minutes of the TV program "Global
Warming" in the buffer, and I can view it by pressing rewind. Looks
like i can rewind the buffer for more than 2 hours too.


However, there is no way to "record" the program that already started
from start to finish. We can only start at the current time... oh
well. Right now I am down with a small flu... so I'd rather watch
it
a few days later than to force myself to watch the 2 hour program
from
start to finish.


is there a way to bypass that behavior, or can i just "save the
buffer" for whatever in the buffer... I have the disk space... just
not the function.


And I wonder why this feature is not implemented, because TiVo has
had
that for several years already. (I think 5 years already).
