Hi guys do anyone know which is the best software to convert dvd9 into dvd5 for backup purposes(as dvd9 discs are quite exp.)

I use a ripper like DVD Decrypter 3.5 to remove protection and rip files to hard drive.

For shrinking (compressing DVD-9 to DVD-5 discs) DVD Shrink is one of the best and it is freely available. The key thing is to backup the main movie only during re-authoring...removing unneeded subs and audio tracks. Less compression equates to better quality copies.

cool thanks for protection I got copy of anydvd anyway thanks for free software

NP. AnyDVD is good too.

DVD Shrink doesn't need it for most DVDs though.

btw, a new hot version of AnyDVD was released. Some interesting improvements (CSS key extraction) and fixes in this version

DVD COPY TOOLS is the best to me. really simple. you can rip the whole dvd or just the main movie
