Thanks guys. Here's the log. I think you're right about the file being so large as to not allow padding. I'm not sure I understand this output, exactly, though. Is it saying that if it splits between cell 11 and 12, then one of the layers will be too large to fit? If so, which layer is now "too large"; i.e., do I need to split cell 11 or cell 12? And, of course, where precisely should I split it?
Accroding to VobBlanker, 1:19:38.06 is the end of cell 11, and the total playing time of all cells combined is 2:42:17.20. Is it safe to assume I should split at the mid-point (time wise) of the (single) title? Or should I really be trying to find a "number of bytes" target, as opposed to a "time" target, and, if so, what's the appropriate bytes/LBA target? I downloaded and looked over VobBlanker's Cell Split window, and it seems to be presenting intra-cell coordinates in "playing time" not "bytes", so it's not obvious to me where to split.
Actually, now that I look again, VobBlanker does report LBAs/sectors, but that's just for the individual cell, not the overall title. According to this link, DVD-9 accomodates 2,084,960 sectors per layer, so, I suppose I should try to split accordingly. Is it safe to assume that all of the non-VOB files will be placed in Layer 0?
Any help on this would be appreciated, in particular, on the suggestion of a very simple freeware dvd authoring application that understands this business of layer breaks and takes care of all of this for me.
