[mythtv-users] dump/import watched show list?

[Robert]

Hi,

I've had a mythtv system at home for a while, and recently installed on at my
parents house as well. I set it up to record some of my favorite shows so I
can watch them when I visit.  Unfortunately, it's recording a lot of old
episodes I've already seen.  I do want it to record old episodes, so I can
catch shows I missed in earlier seasons. But I don't want to have to manutally
go through all these episodes and try an remember which I've seen.

What I'd like to do is dump the relevant info from the database for watched
shows on my home system to a usb stick, then be able to import that data into
the watched shows at my parents house and delete anything from that list that's
already be recorded.

I can cook up the script myself, if someone who knows the database schema can
point me in the right direction for (a) dumping recorded shows and (b) finding
and deleting those shows.

Thanks!
