Hello all, First post, though been a reader and fan for some time. I've been backing up my DVD (all movies) using Shrink and DVD Decrypter for a while now and all has gone well, until now. I've been trying to back-up a DVD of MASH. At first Shrink would not even get through analysis (I think due to scratches) and would say "data error ...cyclic, yada, yada". Took some advice and used Brasso polish. It seemed to help. Shrink got past analysis, but only 50% through encoding and now says "copy protection error. The read failed because the sector is encrypted". Read in a thread a couple of days ago, where ScubaPete gave some tips in using Decrypter. I followed those (installed latest version, normal to aggressive Removal method, removed PUO's, etc...). Decrypter only got 7% complete after an hour with 71 read errors and 1496 retries. I assumed it would not finish, so canceled it. Thoughts? Is the disk just scratched too badly? Two unrelated questions: what is AC3 2-ch unspecified? and why (when using "still image" or unchecking foreign language) do other portions of the DVD increase in size? (trying to strip out unwanted stuff). thanks in advance.
