[mythtv-users] Anyone tried MPEG2 to MPEG2 transcoding?

Looking through the archives I've found that it's possible top set up
MPEG2 to MPEG2 automatic transcoding by issuing the following update
command in mysql:

update recordingprofiles set videocodec = "MPEG-2" where name = "MPEG2";

I want to give this a go because I want to keep my recordings in MPEG2
format but want to reduce the size of the recordings. I can't adjust
the original recording profile because I'm using DVB-T capture cards
which don't encode, they just dump the broadcast MPEG2 stream straight
to disk. So I figure I can reduce the size of them by transcoding to a
lower bit rate MPEG2 file. I need them in MPEG2 format to work on my
xbmcmythtv python scripts frontend.

The question is - has anyone tried this, and what were your results? I
read a post that said the reason you have to enable it via a mysql
command is because it can be a bit dodgy which is why it's not turned
on by default. Should I expect that it's going to play up quite badly
and defrost my freezer overnight, or will it be OK?
