A belated thank you for the response. I have been trying some more runs to try and figure out what was really going on. First of all regarding the menus, I went ahead and played one of the DVDs I had created by letting the AVStoDVD process run to completion even though the Menu editor was still open with the message â€œwaitingâ€ after receiving the path error message. To my surprise, I discovered that the menu I had desired DID in fact show up on the DVD I had created even though the menu editor had shown the path error and had never indicated afterwards that it had run to completion.
I tried recreating this several times and the results were always the same, i.e. I would try to run the menu editor, get the path/file errors, ignore them and run AVStoDVD to completion and find that I had a finished DVD product with the menu I had desired. I have no explanation for this other than that it is a quirk of the program.
On the other hand, after doing this a few times and successfully creating a few DVDs I started getting â€œaudio errorsâ€ which occurred without any additional explanation during the conversion process. I was given the choice of ignoring them or stopping the process. When I chose to ignore them, the resulting DVD would have no audio at the points where the error messages started to occur. I checked the source .MP4 files and they were all fine all the way to completion. Whatever the audio errors are, they are occurring during the conversion process and are not errors in the source files.
Finally, I recently started getting a 3rd type of error when running â€œAVStoDVDâ€ conversion process as well. These messages say â€œError 371 â€“ Specified Object Cannot Be Used As Owner Form For Showâ€. This is apparently a VS Basic message but I have no idea why it is occurring at this time and place.
I havenâ€™t yet tried doing the uninstall/re-install as â€œportableâ€ that you suggested but will be doing so. In the meantime, I have found another free video conversion program called â€œFreemake 184.108.40.206â€ (freemake.com) which is working quite well for me. It has a nice user interface and has been creating DVDs for me in the form and quality I am seeking and without any problems.
