Im not sure if these errors only happen on my machine and if the program should just ignore it (if the audio setting is enabled for a video without audio), instead of failing at the end of each conversion.

Update - to fix it for mkv and mp4, I had to make sure that audio in 'output setting' for each video was disabled, as having the audio enabled when an original video did not contain audio, would give the error. Any ideas on what could be causing it? I am using the codecs that installed with Format Factory. I am using the latest version of the program, v301. Perhaps both of these issues are related to permissions and not being able to write, but even with all protective software off, changing output directory and running the program as an administrator, the problem is still there. I have noticed that after a reinstall, the issue still remains, with the added bonus of no longer being able to drag videos from windows into the program in order to be converted. At 98% the program will hang during conversion and eventually state 'failed'. FormatFactory als Download: Das Freeware-Tool Format Factory ist ein einfach zu bedienendes Format-Umwandlungs-Genie.
