Nero cannot SPLIT bigger files than 700MB?

Hi all,

I use NERO for writing, but I have a HUGE problem. I have weddings filmed, which is more than 2 hours.
I captured to computer, and I tried to use NERO to write to CD at SVCD quality.
Because is over than 700MB, it will not SPLIT into pieces as I expect. Is annoing to use other tools to split in pieces.
Any ideea if I did not discovered how to do?
How can I do in NERO all this and not use 2-3 programs? (time lose)
