Just to correct.
1: DTS wav is currently broken, known issue
2: the mpeg2 file is an incorrect MPEG2 file. It's a PES file, which is not supported by VLC (other then on a Best effort basis). Save your files as MPEG PS or TS files so that A/V synchronization can be garuanteed instead of having to be guessed. The fact that other programs are good at guessing this does not make PES a good file format.
