It would be a very useful addition to MythTV for users who run the
grabber directly (most users I would imagine). I run the uk_rt grabber
and MFDB manually for each source with a single xmltv config, passing
the '--update' option to MFDB. This allows only a single dowload from
the RT site (~12MB for my channels) which can then be applied to any

I am currently looking at adding caching support directly into the
uk_rt grabber (so this would benefit all uk_rt users) and in my
discussions with the Radio Times have also mentioned the possibility
of adding compressed listings files to the RT site in order to reduce
their bandwidth usage even further.
