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

[Phill Edwards]

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?
