1. Is there a Vista version?

No, sorry. Some of the interfaces required are only available in Windows 7, so a Vista version is not possible

2. Is there an XP version?

No, sorry. Some of the interfaces required are only available in Windows 7, so an XP version is not possible

3. Why is the wrong logo shown for my TV Channel?

I don't have global information about channels and logos for all TV channels globally, so I have to do some guesswork. I get notified when someone adds a channel with an unrecognized call sign, and I do my best to google the right logo for it. I'm bound to get it wrong sometimes since different countries have similarly named channels. If I have got the wrong channel logo, put a post on the forum with the name of the channel that you see on the screen and a link to the TV station web site.
