I agreed that current Myth functionality is not well suited to copying
videos from a VCR.

I have several dozen old home movies to archive to DVD, and I'm still
trying to come up with a good way of doing this.

Ideally, I'd like to see a "VHS dub" mode in Myth. In this mode, you
could configure Myth to record for X minutes (ex 120 mins), then hit a
key or button to "begin recording now".

This is different from recording Live TV because you can set an end
time. It is different from the manual recording mode because you can
press the  "begin recording now" key as you press play on the VCR; in
manual mode you have to set the time for the start of the recording,
and then try to press play at the exact time you have scheduled - this
is not a trivial difference.

I'd like to try implementing this myself, and I may try later this
month when I'm on vacation. But my C++ skills are a bit rusty... so
we'll see.

Other advanced functions that I think would be very useful in a "VCR
dub" mode would be "blank screen detection." A lot of my home videos
don't use the whole tape. Consequently, if I dub the whole tape onto
the computer, I often end up with 10-20 minutes of blank, blue screen
at the end of the tape. It would be great if this could be marked
automatically, in a similar manner to how commercials are detected.

Anyway, enough daydreaming for now...
