I am using dvd decrypter to rip and store movie an an iso.
Do i always have to use this program to burn with or can i use nero, tried with Nero had not got a clue what i was doing.tried to grab files across to video file would not have it.

This is all new to me

it all depends on the source material,you could use file mode as opposed to iso and put all the vobs,bup and ifo etc in a VIDEO_TS folder and burn using nero,but i would use the likes of record now max (data mode) for better dvd compatibility.BUT this will only work if the source file is under 4.3 gig or it won't fit on a dvdr,anything over 4.3 gig and your going to have to use another program to compress the size of the file to fit on a dvdr(i.e-dvd2one,tmpgenc,instant copy etx,etc)but if its 4.3gig or less dvd decryptor will make a perfect 1:1 copy,so no need to use and other burn software in that case.

Thanks
