The site states that their Wondershsare Video Converter Pro software will convert to play on an NTSC video player. However it cuts off at the end of the DVD. They also state a refund will be given if the software does not work and they cannot provide a solution. This refund policy has mysteriously disappeared from their website.
After getting the run around from their technical department asking unrelated questions to the stated problem and offering non-working solutions they concluded I would get no refund as they cannot determine the problem is their software.
I am using a brand new iMac and am now using a different product that works fine and offers a money back guarantee.
Do yourself a favor and void the headache of dealing with this scam of a software company.
