My CD-RW (Lite-On 16x10x40) supports overburning.

I use VCDEasy to burn VCD's (thus, CDRDAO)

So far, I've overburned two SVCD's, with sizes: 808 Mb and 816 Mb

No errors were reported either time.

Questions:
1. if there was a problem with the overburn, would I get some indication in the VCDEasy Log?
2. in case of failed overburn, what part of the video would get chopped off, the end or the start? (Actually, I'm guessing the lead-in or lead-out would be affected, and the resulting CD would be unusable)
3. How far can I go with overburning?
