Thank you Moritz! I will at least consider doing that, but I was beginning to suspect a bug myself. I just need to find a solution or work around first before I can take the time to do some more testing with VLC to confirm a bug. VLC allows you to use ffmpeg to convert a video from the command line and I want to see what the output looks like before I report a bug.
