I bought a program, DVD ripper for Mac to back up some of my DVDs
The program took so long , sometimes 20 hours to rip and often would not finish the job
I contacted their tech support and tried some of there suggests but it never fixed the problem
They had a 30 day money back guarentee but would not honor it.
I have kept up emailing them but they will not give me a refund
Hope that is enough
