Corel VideoStudio Pro X4

When chapter points are created and named with specific content-based names in the Edit/Timeline stage or the Disk-Authoring stage - aif ONE chapter point is deleted or added either in the timeline (leaving the time code for the other chapter points untouched) OR in the disk menu, then ALL this information, all the specific chapter names is obliterated and AS WELL the customised background images and music revert to the Generic menu - ALL The Work is Totally Lost
If a Transition is altered/added to Chapter Points, the Chapter Points are moved along the video timelines a considerable distance from their original insertion point vis a vis the video track appearing 1-3 seconds after the chapterlead. All The other Work in the Disk Authoring Stage Is Lost - poor "Ripple Effect"' facility
Export Function Is Compromised - producing unreliable .mpg and .avi.
Import Function is much better including all high definition formats. Does Not import VOB files.
The frills and special effects are Excellent. But It Fails On The Most Basic (Free) Entry Level Functions. It Is Poorly Integrated between Timeline and Disk-Authoring - a huge amount of work is lost because of its ineptness in dealing with simple actions that other programs in 2003 had no problem with
It Is Unstable. It Freezes Despite The Resource Monitor Showing Large Amounts of Spare CPU and RAM. A Disaster - for what could have been a wonderful program. Get The basics Right.Its Export Function Is Compromised producing unreliable versions of the most common formats - .mpg and .avi in particular have one holding their breath.
The Email Support Service of Corel pretends there is not a problem and then will claim that the case has been inactive 10 days despite a flood of emails well within the period. They tell the customer that "the problem has been resolved".
Does Not Meet the Basis Standards Of Integration and Stability! - - A Pity because The Frills Are Excellent.
