Your 830 MB might fit an 80 min/700 MB CD as SVCD without overburning. It depends how you calculate the megabytes. This is the maximum limit without overburning on a 80 min/700 MB SVCD:
80 min CD
= 360,000 sectors * 2324 bytes / sector
= 836640000 bytes
= 797.9 Mb

With overburning enabled you may be able to burn 20 MB more on a 80 min CD and 100 MB more on a 90 min CD.
If you still can't burn it to one CD then bbmpeg is a great SVCD splitter. First demultiplex your big mpg file with TMPGEnc MPEG Tools. Then multiplex with bbmpeg but set max file size to 795 MB. This will split the output to SVCD sized mpg files that you can burn as SVCD's with Nero. If you are lucky the cut was made in the end credits so you may not need more than one disc anyway.
