When I start DVDDecrypter, my firewall tells me it’s trying to contact various sites, including:
update.dvddecrypter.com
www.btinternet.com
www.google.com
www.microsoft.com
www.yahoo.com
It looks like it’s looking for program updates. Anyone know, though, why it would check these sites for updates? All but the first one seem un-obvious to me.
Also, I can’t find anywhere in the settings to disable this check. Is it hidden in there somewhere?
try unchecking “Check for updates” in settings-events
i think it was advice on the dvddecrypter’s homepage for peace in mind
D’oh! Why didn’t I see that when I was searching through all the settings? Sorry about that! 
Tools>Settings>Events>untick check for Program Update. I hear it is wise to also block your firewall for dvddecrypter, I suppose to disallow your potentially being tagged for maliciousness or worse, receiving a court order to surrender any dvd’s you may have as well as your HD for removal of dvddecrypter.
My best to all,
