Cool.

Please!  When you give a command line and it's output and complain
that "it's not working", _do_not_ edit the command line.  In your
above command, you removed the _most_ useful (and only important)
part of the command with your "<time/sec>" instead of putting in the
value you really used.  The time you ran the command would also have
been useful.

Please provide the command line and _all_ of it's output (up until
mp1e starts writing status lines anyway) of some samples of:

$ date; record --channel 45 --end <time/sec> test_file

Did you read the mp1e manpage when trying to debug this?  -n <value>
is the number of seconds to record.  As you can see, whatever you put
into "<time/sec>" was calculated to be 10.139722 (36503 / 60 / 60)
hours long.  Knowing the time you ran the command and the value of
"<time/sec>" would help in debugging.

-n <seconds>

Nope.

Yeah, more "local" hard coding.  I really do need to put some
"autoconf" smarts into the openpvr code in general.
