Hi! I've been using DVD Shrink for awhile, never had any problems... Recently I was giving it to a friend, and suddenly the application stopped working. Double clicking on the exe, shortcut, anything.. produced 0 results. The task would launch for 1 microsecond, then die, instantly. Reinstalling seemed to fix this issue... so I figure it's a bad windows install, I try a totally different XP SP2 disc... same problem (works fine after install, some random time later, stops working) I've actually reproduced this on two completely unrelated computed (except both have SP2 installed?) I'm completely at a loss as to what could be causing this (considering I don't see a very large abundance of this issue, it can't be JUST sp2, but I'm seeing it on every computer I try) Oh! And I noticed this... whenever the application ceases to work, the filesize is 300kb~ bigger. It starts out as 550ish KB or something.. while it's operating fine it doesn't change, boom program stops working.. file size is now 786kb.. MD5sums do not match for the 'old' file vs the 'original' file. I've tried to set read only on the file, only to have the problem happen WHILE DVD-SHRINK WAS RUNNING. Does anyone have any friggin idea what thing could be? I'm a pretty tech savvy guy, and this has me at a loss. It's not DEP, that's off. The filesizes and the files themselves are being modified (just the exe) and I have no idea how. No long, no change date.. just a sudden change.
