Conversion of DVB-S2 files from a Technisat Digicorder HD S2 Plus?

[Phin123]

Hi there,

I got a Technisat Digicorder HD S2 plus. Its a pretty nice
receiver, it even lets you natively copy the recorded movies
via USB or LAN to a computer.

But unfortunately I didn't found a convinient way to convert
the *.ts4 files to something usable/editable under WindowsXP.

Today I had luck with this method:

Using TSremux on the TS4-file toremux it to a M2TS.
Then I can convert it using TMPEGenc Xpress 4.0. Unfortunately it looks like that it can't encode or streamcopy
the original AC3-stream... if I use TSremux to demux the
audio and use it then in Xpress the sound gets out of sync...

Any solution for transportstreams with H.264?

kind regards!
