I was about to author a DVD with a bunch of Harold and the Purple Crayon episodes (heh, it was my favorite book when I was a kid!). Anyway, the files add up to about 3.2GB, but DVDWS is stating space required as 4.9GB. Is there really that much wasted space? All the MPG's have been patched to 352x480, and there's lots of free space on the drive.

from reading other forums, it looks like DVDWS re-encodes the mpeg's unless you...

"In order for DVDWS to stop re-encoding your mpeg2 files , on the Finish Step, when you choose Make Disc, simply set a bitrate HIGHER than the one you used for encoding your Mpeg2 file."

i don't use DVDWS, so it' just a guess...

Good Luck!!!

No, I just did a DVD with 4.36GB files and the end folder was 4.36GB (the menu and other files are less than 800K).

What you can do is use MovieFactory2, start project, add video, then you can find which is giving you reencoding time/size. Let's say your clips are 400MB when you add them to MovieFactory they will show as 400MB more/less a little, if you find one that jumps high then maybe is not patched right or have some other attributes that DVDWS doesn't like.

I just added a 423MB file (patched to 352x480@3.5) and it shows in MF2 as 429MB, so no reencode for this one.

And a 332MB file (not patched, so is 480x480@15), say 1.2GB out of 4.7GB, so this will be reencoded.

Well the problem is, I've got 13 clips, and in DVDWS they all show as 352x480. I suppose I can start over, just hate to spend all the time waiting for it to do it's thing (you know, the part where it's dead slow and you don't know what it's doing.)

UPDATE: That was it Fugg. I changed the bit-rate to 9000 and it was happy. Thanks for the tip.
