"The current dvd size is too big"

I get that message when i try to backup three mpeg files which were merged and turned into a video_ts file with dvd shrink. It isnt even a great quality video, why wont it fit onto a disc, or how do i make it fit?

 

Well i burnt half of it onto one disc, but it wont play, on any sort ofplayer. the media is ok, its ritek, help.

 

shrink it once, then shrink it again.

 

How do i shrink twice?

 

shrink it, then open dvd shrink and shrink those files again.
