These are some trimmed TS files output by DGIndexNV:
http://horman.net/switch.ts
http://horman.net/titles.ts
The first file is the very start of my recording, which includes a switch in the main audio track from stereo to 5.1.
The second file starts further along, so the main audio track is only 5.1.
Both have a second audio description track and some subtitle streams.
