I can now confirm that my problem, as can be seen in this video here
is present in all versions of Imtoo DVD Ripper Platinum Pack or Ultimate Pack from version 22.214.171.1243 onwards. Version 5.0.44.0925 was the last version that didnt have the problem that I mentioned above.
I have tried all version from 5.0.44.0925 onwards to the latest builds of Imtoo DVD Ripper Platinum and Ultimate, on both Windows XP and Vista, on on 4 other PCs, 2 on XP Pro and one on Vista and one on Vista SP1, and have also tried tried with 2 Win XP Pro SP3 VMWare image, the problem remains. I have tried selecting the output as divx.avi, and then xvid.avi, then normal .avi, .wmv and even to iPod mp4, and the problems is still the same
I sent personal emails to tech support, and their suggestion of "Force Progressie 24 Hz" using Tools-> Settings -> DVD didnt work. I even played with Audio/Video Synchronisation, nothing worked.
Conclusion, Imtoo software introduced this first 3 seconds bug in every version from v 126.96.36.1993 onwards, and it still remains. So make sure you test your software properly before you decide to buy.
As for me, I have to look at other Imtoo/Xilisoft/4Media alternatives, as they sell the same software with different skins suffering from the same bug.
Hope that helps some one.
