I looked into the link you provided and it offered some
file sizing suggestions. Not familiar with the software being used, I do not have any suggestions beyond what you may have already tried.
However, I have an idea to experiment with.
First and foremost, make sure you
make a backup copy of a file you are willing to experiment with.
Secondly, check to see if you have Windows Movie Maker packaged with your Windows OS.
If you do, this is where the ‘experimenting’ part comes in. Since you have a .mov file you may need to convert it to something WMM can handle. If your version of WMM won’t accept .mov files, download and install a free utility called
Format Factory. I recommend converting it to .avi for overall compatibility.
The conversion process can take anywhere from several minutes to several hours depending on file size… be prepared to be occupied doing something else during this process.
Once the conversion is completed, you can then filter it through WMM (I recommend NTSC 2.1 MBPS). This, too, will take… time.
Once finished, you *should* have a .wmv file that is only a fraction the size of the original. If this *experiment* has worked as well I have done in the past, you will be able to burn DVD’s with little or no loss of quality and much smaller file sizes.
