DVDSanta error message: Error Trace

I have been successfully using DVDSanta to burn my downloaded movies until I met one movie the it refused to convert and burn.

I get the message: Error Trace: key, ACS, ASCQ, ASCLEV = 3,c,o,a

I am transferring it to a DVD-R instead of DVD+R because I was able to buy 100 for 4.99 on Black Friday. Do you think that has anything to do with it? I put one other movie on DVD-R and it transferred and played with no problem.
