Had no such problem with PD6
Have installed vs 1829, crashing on importing more consistently than vs 1714
Have installed vs 1911, crashes all the time when importing DVR-MS files, Can import VOB and WMV files and burn DVD ok, but not DVR-MS
Have rebuilt C: drive from scratch with Vista Ultimate so that PD7 was the only programme installed. Still crashed as soon as file was clicked on to OPEN
Have done all procedures noted in Forum for cleaning out all older copies of PD7 and the install programs,
Have followed Help Lines extra steps to delete installation files in the registry, prior to a new install
Have deleted all Cyberlink folders as directed
Have updated correctly VGA drivers and have checked compatibilty of DVD drive
Have supplied Help Line with several dxdiag.txt files by now and a few screen dumps just before I click on OPEN a DVR-MS file, after which it immediately crashes with no error messages and no warning.
And as you have guessed by now Help has not been able to help me and seem to provide the same platitudes to me as everyone else, "A new re-install will fix it" well it doesn't, not even new updates.
When looking through the registry it appeared as though PD7 was everywhere, you'd have to wonder whether there is a basic registry problem somewhere, with so many entries from just one programme.
PD7 works equally well (apart from the OPENing problem) in 1600 X1200, 32 bit colour as in 1024 X 768, 16 bit colour.
If anyone could suggest what is wrong with this basic opening and importing step for large (6.0GB) DVR-MS files your help would be much appreciated.
