.mpv´s smaller than D2SRoba setting

Hi there,

I´m trying to put about 4 hours of video (2 movies in 4 .avi files) into a DVD-r. To automate the process I made a batch in SVCD2DVD (using RoBA plugin, with no images, so I can edit the .mpv´s and .mp2´s with DVDLAB). Well, I set D2SRoBa CD size parameter = 1110 for every .avi (4440 mb), but look at temp1 and temp4 folders diff´s:
why only the last avi has the right size?
