My system would occasionally lockup (or recode would simply crash or fail to import the dvd) with Recode and Anydvd when importing titles on anything other than my burner (this is a known bug with Recode where two or more drives exist, in my opinion, since I can duplicate the problem on more than one system--and given that other people appear to have the same issue; moreover, someone working for Nero essentially acknowledged this issue). My systems are very stable and do not require OS reinstalls, formatting, incompatible driver/software removal, or anything else.
Perhaps I am misinterpreting the OP, but I interpret "operation" from "Sometimes also my PC boots during the operation" to mean only the process of attempting to backup Daredevil using decrypter and anydvd. Were this rebooting to occur at random, during other operations, or with other dvds (using decrypter and anydvd), I would wholeheartedly agree with you and whisperer1. Otherwise, I suggest using Anydvd ripper instead of decrypter to rip the movie to one's harddrive (regardless, I would recommend doing this even if decrypter were working perfectly fine for the OP).
