Within VideoReDo's options there is a setting under the
"General Parameters" to have it "Output Streams for Movie
Factory" , perhaps you should check that box.
A good general description of DVD compliant MPEG,
from the TDA help section:

GOP structure Max. 18 frames (NTSC)/ 15 frames (PAL) Max. 18 frames
(NTSC)/ 15 frames (PAL)
Sequence header interval One header per GOP (one sequence header in
front of all GOP) One header per GOP (one sequence header in front of all
GOP)
VBV buffer size 40KB 224KB
You can use parameters that exceed these sometimes and still
have it work with most players, but this is a useful starting point.
( Don't know if the formatting above will work, I was surprised
it made it here with the Ctrl-C & Ctrl-V process.)
Luck;
