System.ArgumentNullException: Value cannot be null. (Parameter 'nextSibling')

[guiltyjudge]

What were you doing when VidCoder crashed?

Batch transcoding files seems to be an issue with decoding subtitles and keeps popping up exception errors I'm not sure if this error will attach otherwise I can try and upload to imgur or something. I have rules set to pass through english and unknown subtitles to account for unlabeled subtitles.
