The DVB-C apparently is producing a non-standard AVC file.
What do you mean by a "TS file"? Do you mean an MTS?
What model of camcorder is this video coming from? It would be best to edit it in its native format rather than convert it to a format that is, apparently, not compatible with consumer software.
Thanks for the fast reply!
It is a *.ts file. VLC gives following codec information:
Codec: H264 - MPEG-4 AVC (part 10) (h264)
Codec: A52 Audio (aka AC3) (a52 )
>recorded via DVB-C
Is that a camera, or software that records some kind of streaming video?
It is likely that with video recorded from a TV broadcast signal, you are getting a stereo/2-channel Stream for the commercials, but the TV show is in DD 5.1 SS, and you are only getting part of that - probably just the LS and RS channels. The LF and RF, plus the Center Channel (where most dialog will usually be), are being lost.
Not knowing your recording program, I cannot tell you how to adjust it, for DD 5.1 SS capture and output. That will be a DD AC3 Stream too, but 6-channel, and not 2-channel.
Well, that is what I expected too.
But I think that the problem is caused by PrE (maybe an incorrect setting) because WMP plays it normally, even tough I have only stereo PC speakers.
Could it help to demux and remux the file? If yes, how to do it (without buying additional software)?
It might, but only if the full 6-channels are included in the Audio Stream. If so, many programs, like Adobe Audition, can extract each channel, to be edited separately. Then, one could adjust, say the LF, RF and Center channels, as needed.
Though in a playback environment, I had similar with my master bedroom home theater system. I had a single-stage video receiver, which was DD 5.1 SS, and did a great job for just the bedroom. However, I had the audio feed going to the master bath, as well. That did not work well, as the stereo mixdown came from the LS and RS feeds ONLY. Hence, when there was a stereo signal, then I got good audio in the bathroom, but when the source was DD 5.1 SS, I only got LS & RS, so all dialog was missing. To counter this, I upgraded that receiver to a two-stage unit, and the second stage did the complete mixdown, of ALL 6-channels to traditional stereo, and suddenly, the dialog appeared from either 2-channel, or 6-channel source material.
The first thing that I would do, would be to take one of your video files, and run it through G-Spot, or MediaInfo, to see if you ARE getting the full 6-channels (or at least the "big 5," LF, RF, C, LS and RS - LFE is not really necessary, except for Hollywood productions, where there IS real LFE material). If you have 5 - 6 channels of Audio, then a program, like Audition, can help you out.

There should be 6 channels.
OK, you do have 6-channel, so you can use one of many audio-editing programs (do not know that many, as I use Adobe Audition almost exclusively) to get what you want. I would go for a sub-mix of LF + RF + C, and leave LS, RS and LEF out, unless you want the LFE's and some ambiance from the LS and RS.
PrPro CS 6 has the ability to breakout to mono, for 6-channel Streams, and one can map, re-map or use sub-mixes to get what you want, but I do not think that there is a way to easily breakout a 6-channel Stream to the mono components.
