I have PowerDirector Ultra 11 (build 11.0.0.3230 - SR # = VDE130812-01), Win7 Prof., 64 bit, Intel i7 CPU, 2.93 GHz, 6.00 GB RAM.

I'm having trouble rendering a movie which is a combination of .mov and .VOB clips. The preview looks good (after I rolled back the NVIDIA driver). The .mp4 rendering [640x480/30p (6 Mbps)] results in flickering in spots. I reduced the problem to combining 2 short source clips with different original video formats:
A.mov: file type MP4, video type H.264 AVC, 4.29 Mbps, 1280x720, 30 fps, progressive
B.VOB: file type VOB, video type MPEG-2, 5.24 Mbps, 720x480, 29.97 fps, interlaced

Rendered separately into separate movies, there is no problem. However, when combined into a single movie, there is flickering that occurs in several spots in the A.mov portion of the finished movie.

I thought that PD would be able to edit video clips from different sources and render them into a single output file. Since that did not work, I tried to render the .VOB file into a .mov file using PD, and then import that back into the workspace, in order to then combine files with more similar attributes, but that did not work even before rendering. It froze up my system when I tried to import the new .mov file into the library to join the previously loaded A.mov file, and when I imported the new .mov file into a new empty project (which worked better), there was an error message when I tried to drag it into the editor timeline workspace: "Media Source Error [Error COde2]: A media file in your project may not fully comply with the file format standard, or your system amy lack the required decoding components for this file. Please try again using another media file format." I was surprised to get this error, from a file output by PD itself.

Thank you for any help you can offer concerning this problem. If you need any more information, I will try to provide it.

Note 1: I am attaching MediaInfo files for the original sources of A.mov (11-02 Memorial.mov) and B.VOB (VTS_01_3.VOB).
Note 2: I just now found the update to PowerDirector 11 to build 3625 to
improve compatibility with NVIDIA display driver version 331.65. It would have saved me many hours if the PD update had come out sooner, or perhaps if I had seen the update earlier, because my previously good preview had stopped working, apparently after I upgraded my NVIDIA driver to 331.65. I finally discovered that that was the cause, and I rolled back the NVIDIA driver to version 9.18.13.3158. This is how I have run all my tests with PD described above, with the previous PD build 3230. I don't want to change anything now, if it's not necessary, since the PD update only seems to affect the NVIDIA driver issue, which was corrected when I rolled back the driver. I have run multiple tests and spent many hours reducing the problem to the form described above. If necessary, I can update the NVIDIA driver and PD version and rerun the tests, if you think that might be a pertinent factor.
