Thanks for the answers guys.

I can confirm that I am already using the xmltv generated time-shifted
channel (tsod.plus-1.more4.channel4.com), however I have just looked
via Mythweb something somewhere seems to be changing the data. EIT is
off on the channels (never very reliable from DVB-S)

I will have a trawl through the database at some point and double
check EIT is off, but everything I can see says it is.
