* Problem 1
* There is a small problem here... What happens if the DVD has no Subtitles? or Handbrake misses the Audio or Chapter track

*
* hbcli will sit in a suspended state until it is forcefully closed.
*
* Problem 2
* See AudioTrack.cs Line 80 for details
*
* Problem 3
* Doesn't seem to support DVD's where the first track is 0 instead of 1, and only includes 1 title (TS/MPG files)
* Simply Doesn't list any titles.
