Getting GOP Error from TMPGE DVD Author after CCE Encode?
 

I'm trying to put 3 movies on one DVD-R using CCE and KDVD templates, but I'm getting an error from TMPGE DVD Author. After encoding I got a frame rate error, so I had to use pulldown to resolve that. However, after doing that I get the following error when loading into TMPGE DVD Author:

"The video GOP is too long.
For a standard DVD it is necessary that the GOP fulfill the following conditions:

Max 36 fields {18 frames) {NTSC format only}
Max 30 fields {15 frames) {PAL format only}"


Here is my script:

# ( Portions from AviSynth's manual ) - This will apply temporalsoften to
# very static scenes, and apply variable blur on moving scenes.
# We also assign a variable - and this is why a line break is inserted:

SwitchThreshold = (Width<=352) ? 4 : (Width<=480) ? 3 : 2

This is my first attempt at KDVD using CCE, so in unchartered waters here. Any suggestions would be appreciated.
