How to convert DTS audio from .ts?

[Chupacabras]

I have some movie in .ts format (playback is flawless).
Video is MPEG2, audio is DTS. It has 26GB so I'd like to convert it into x264 and AC3.

I have no problems with decoding and recoding video, but problems are with audio.

Some of demuxing applications (dgindex, projectx, bbdemux, tsremux) are not able to demux that DTS audio stream. Then I used mencoder to demux it:
mplayer -dumpaudio -dumpfile x:\audio.dts x:\movie.ts
mencoder -ovc copy -oac copy -audiofile x:\audio.dts -o x:\avi_out.avi x:\avi_only.avi
(avi_only.avi has video stream only, it is original video converted from MPEG2 to x264)
But every player shows that movie is 3 times longer, playback is like fastforward, audio is jumpy like the video.

How to convert or use that DTS stream?

Were you able to demux it finally? If yes, you can use eac3to to convert the dts to ac3.

eac3to didn't work.
eac3to can convert eac3 to another format, but i have DTS audio, not EAC3.

You are wrong... Have a look at the 1st post in the eac3to thread.

I had a similar problem several days ago with a mpeg2/dts ts file.
In my case, the only working splitter was the Gabest mpeg splitter.
So, I successfully demuxed the dts track using the Gabest splitter/Dump filter in graphedit.
What is your flawless working splitter/player?
