I have AMD 1800 processor, Op Sys is XP Prof, I use ANYDVD 18.104.22.168, CloneDVD 22.214.171.124 and make temp copy to my hard drive (C), then transfer to blank media single layer 120min DVD+R at 8x with no problems. BUT this time I am unable to make a back-up DVD copy of 3:10 To Yuma since the D drove stops copying the source disk and I get a window message saying "Processing Error:/VIDEO_TS/VTS_01_vVOB:read error - Data error (cyclic redundancy check). File 1 D:/VIDEO_TS/VTS_01_4VOB23 TCSectorReader". I read previous threads re 3:10 and have removed the < and > but still cannot finish making a copy of the source disk. Any Easy To Understand Help Or Answers For Me would be appreciated.
