I have tried to download the update for the ENGINE listed on the download section but it just send me to the support section!
Then support tells me I need to pay for any upgrades, 6.4 is available but will be classed as a paid upgrade. I have had many software packages in my time
and the .X OR THE INCRIMENTS BETWEEN FULL NUMBER VERSIONS ARE FREE is this not the case with DVDITPROHD
Sorry if this is a NO BRAINER to some, just my experience. Have owned DVDITPROHD for a while But only just started to use it and so far I am happy, but would have liked some more features
