Made a couple of projects (one based on AVI-files and one on DVD-files).
As soon as I hit the "burn to DVD" button from the preview window, DWS2 crashes and Windows XP freezes. It takes AGES to warm-reboot.
After having gone through numerous threads on this forum:
- uninstalled Nero InCD and any program that is reported to be suspect.
- un- and re-installed DWS2 (completely).
No change.
Uninstalled MSP8 and DWS2 (thoroughly as described in other threads).
Re-installed DWS2... and it works fine.
Installed update patch 4... and it still works fine: I can burn to DVD, to DVD-folders and DVD-image file.
Installed update patch 5 and problem is back.
Uninstalled everything again and re-installed DWS2 with patch 4 (last known working environment), then installed MSP8. Problem is back.
THEN overwrite files in Common ULead Files DVD folder with those of initial installation (kept a copy of the folder after clean install). Works fine... except that I have no more audio in the DVD-files based project (at least; that is the only problem I have come across sofar).
Uninstalled everything (must be about 20 times that I did that now) and installed MSP8 first, then DWS2. Problem stays.
Tech support so far has done nothing else then to advise to un-install and re-install the program with the latest patch and asked to send my system info to them a week ago... have not heard anything back yet.
How can it be that a patch and/or a program from the same company make another useless???
I have had EXACTLY the same problem in the past with DMF5. 
(That was solved after tech support sent me a link to a new download version.) However; that program did not live-up to (my) expectations so I purchased DWS2 for more flexibility.There MUST be a way to pinpoint the cause of the problem
Anybody any experience from the past?
