Hey Jaidev,
As channel 4 I have national, it has: to be announced instead of guide data and UKTV is missing all together. I ran throught your dbset commands for changing and existing channel's FSID, Name, Station etc and all worked APART from FSID (e.g I have UKTV showing as 4 again but still no guide data as it'll be seeing it as national still). But this may all go away once I re-image so not to worry too much.
