Missing schedule data

[masterjay2]

Hi there. I've recently downloaded tv-browser for mac and it's great but, I'm missing a lot of data on channels. These channels are:

ITV3
ITV4
All Sky channels (sports, movies etc.)
All MTV channels
A few of the music channels

The schedules just aren't showing up. It's totally blank. Any ideas why? I'm from the UK and last time I checked they were working on my laptop just not my mac. Any help would be appreciated!

Do your system and TV-Browser have the correct time zone?
