Add manual recording - default time

[markn62]

Have an old past request for a global max recording length setting, like 15/30/60 min, but didn't pass muster. So I schedule recordings from the guide except for shows over an hour I schedule manually which is cumbersome. To make it less so, it would be nice if the scheduler didn't default to 20:30 but instead auto populated with the current time. Or at least change to 20:00 so the 30 doesn't always have to be changed to 00. Thanks much.
