[mythtv-users] can't play .18.1 recordings on .20 system

[Craig Yuen]

i'm building a new frontend/backend system using ubuntu 7.04/mythtv 0.20.
i've extracted the mythtv data from the database on the old system and
restored it to the new one and have copied all the old recordings.  when i
run the frontend, i see the old recordings listed but they can't be played.
i can play new recordings.  the frontend gives the following messages:

it looks like the backend can't find the old video files, are there
additional steps needed to move recordings from an old system to a newer
one?

thanks.
