Can not upload more then 6.40 hrs of a 14.hr program

I have a Tivo series 4 elite. I recorded the 5 days of the civil war for a total of 121/2 hrs. I used Kmttg to download the programs to my computer. I used Vedioredo to edit out the start and endings and then used the Vrd joiner to join the 5 programs together. The total came out to a 14 hr 40gb program.

I tried to push 2 times and tried to pull 2 times but I can only get 6.40 hrs to the tivo. Would any one know why it will only do 6.4 hrs?
