after using smartripper & rempeg2 on the film panic room
ac3= 352,296
m2v=4,194,304

Are they too big to be put on dvdr?
if so, how do i reduce the file sizes??

Thanks

Well a DVDR is 4,700,000,000bytes or 4,589,844KB and
352,296+
4,194,304

4,546,600

Although I can't help but notice that your M2V is exactly 4gig to the KByte and you did say in another post that you were running FAT32. Which brings me to another point. You have like 3 posts on Panic Room, this just makes things confusing, in future please try and keep all relivant points/questions, etc. in the one thread.
