i have been using dvd shrink for 8 mos sometimes with dfab decrypter and burn w/ nero 7 w/o probs. just a week ago everytime i open dvd shrink my computer hangs. the cursor won't move, ctl+alt+del command won't work. i have to press the reboot button and start from the beginning again. can somebody please share their knowledge regarding this problem. i tried removing the software & downloading a new dvd shrink but my pc still hangs when i open the new dvd shrink program. ps: i remember before this problem started i tried to shrink a dvd-"transformers" which was downloaded from the internet. i was not able to shirnk it and cannot watch it w/nero and windows video player. i was able to open it w/ power dvd but w/ great difficulty.
