So far as support for the new xmltv functionality in Myth is concerned, one of
the things that has puzzled me with the existing setup is this: Why is it
necessary to have a static <sourcename>.xmltv file for UK users?
Because of this, it is necessary for the user to keep three things in step: the
relationship between the RT ID and the xmltvid; the list of xmltvids in
<sourcename>.xmltv, and the xmltvid relationship to the channel concerned in the
If one edits the database via the frontend or via mythweb, one also has to
remember to edit *in step* the related <sourcename>.xmltv file. This step is
easy to forget, which means that the next mythfilldatabase run promptly adds
back in channels where it finds a discrepancy. And one has to make sure that any
copies of this file under various userids are also kept in step.
I suggest that after the initial mythfilldatabase run which (through use of a
switch) builds the correct channel:RT ID relationships, mythfilldatabase
subsequently just extracts the xmltvid list from the database when required,
possibly as a temporary <foo>.xmltv file. This would ensure that the various
linkages are kept in lockstep.
I did look at the relevant code a while back, and it seems that, as the UK
portion of the code is tested for separately, this shouldn't be too difficult to
