dvd way too big?

[item9]

ive put together a 14 gb dvd and was hoping to shrink it to a dvd9
to burn, but all programs like dvd shrink or dvd fab seem to only
output 2/3rds of the video...
i watched the vobs directly and the video is all there
when I open up the files with dvd shrink and preview the video, its
all there...but any dvd i output is missing at least 2 hours of video...
i put the video together with womble mpeg-vcr
demuxed the mpg and used ifo edit to author the dvd...
ran the files through vtsfix (dvd shrink would open the files until i did this)
is there some files size restriction im faced with?
should i go about this a different way?
thanks for any help...

Use dvdfab to split it to 2 dvd9 or re-encode at a lower bitrate,if its 4 hours then the bitrate can be around 4600 kbps for a single dvd9.
