Some how I successfully batch converted 300 swf files using the unregistered version of iWisoft Flash/SWF to Video Converter. I did two runs 200x148 and 640x480. Now that my project is moving forward I registered and tried to run the batch job again for some reason all I can produce is 15K size files that only have black screen video. There are lots of settings options of which I have tried a few different ones trying to find the sweet spot combination that worked before. Any ideas?

Sometimes if I run a single file (not batch) and if the PC is rebooted?? it will work. Not sure about the necessary combination. It is still a little random to me as to what works and doesn't.
