Why cant I play my recorded dvd from lvc-9006

I recorded a program off of my DNetwork dvr that was saved, to the 9006, and it played fine on the 9006. When I put it on my computer dvd player it just kicks it out. I tryed a purchased movie on the computer to verify its operation, and it worked fine . I just want to get the files on my computer so I can edit out the junk !!! Help will be appreciated, Thanks, Bob

Did you finalize the disc in the 9006 before putting it into the computer?
