What does this error mean?

[wgw]

cce encoding failed: VBR VBV ovf frame# 39 (00:00:01:14) B 44912 max 44589.78 pln 40868.54 rel 322.22 1.01 qsv 96.00->96.02

CCE SP 2.67.00.10
DVD-RB v.52 (one click mode and dynamic cell bitrates enabled)
Source DVD: Sex In The City Season 01 Disc 02 NTSC.

Until now, I have made dozens of successful backups with no errors. First time I have seen this error during encoding. Does this mean a frame is out of range for DVD standard? There are several frames that exhibit this error. Can I click OK and continue the encode and ignore this error?

If I recall correctly, I had this and got around it by reverting back to 2.66x from 2.67x.

Thanks a lot guys, the solution I chose was to run the source through DVDShrink at 97% compression before using DVD-RB/CCE. I figure such a minimal compression with Shrink would have little impact on the final output. Looks perfect on my 30" HDTV anyway.
