Hi. As a newcomer to this area, it is very noticable how much comment is generated on DVD production from PTE when users try to use Ulead software, so I'd like to throw a few points into the melting pot, if I may. Let's leave out the custom avi approach for the time being. PTE offers what appears to be a simple and straightforward way of producing DVDs, by simply ticking checkboxes to use Adobe, Pinnacle or Ulead software, then loading the relevant package and burning the disk, remembering of course NOT to click on the 'Finish' button in PTE until the whole job is finished! It would appear that it generally works fine with Adobe and Pinnacle, but Movie Factory generates quite a few comments. This is what I have found. Observation 1 : When you tick the box for Adobe or Pinnacle, PTE will produce a file with an .avi extension, as you would expect. With Ulead, it creates a .ptev file. Observation 2 : PTE uses Movie Factory version 2. This program has long gone - we are on version 5 now! I have used version 5 for the DVD process and it doesn't recognise the video file produced by PTE. I'm led to believe theat the same is true for version 4 as well. A number of comments in different threads seem to confirm this. So, is it that PTE has not moved on to take account of changes in Movie Factory? Where would you get Movie Factory 2 from now, and why would you want to anyway? yes, I know that every time this issue crops up, people chip in with workarounds using custom avis, but that clouds the issue and is missing the point of why the tickbox approach doesn't seem to work for certain versions of Movie Factory. It would be helpful if Igor could clarify whether the problem is related to which version of Movie Factory is used, and what the situation is likely to be in PTE 5 when that element is implemented. (Is ptev an old codec? I can't seem to find it anywhere now? Thanks.
