Lossless conversion of imperfect TS (with sound dropouts) ?

[povlhp]

I have a TV show recorded from sat. It is in an MPEG TS container. containing an MPEG-2 video stream, and a MP2 192k audio stream. That sounds perfect for remastering to DVD using ffmpeg and copy.

My problem is, that I have holes in the sound. 100 breaks are detected in MPEG Streamclip (I am a Mac user btw). So when I treat the 2 streams individually, the sound file ends up being 6 seconds shorter than the video, getting all out of sync.

If I play the original TS in VLC, all plays fine, and sound /video is synced. If I export it as DV from MPEG Streamclip (thus causing recompression), all is fine.

But ffmpeg never resyncs the sound again after the holes. Is there any way I can force it to do so ? Like "keyframes" that is used to re-sync audio and video ? I want this without recompression, as it works fine if I recompress and thus changes quality.

Should I use another tool ? Maybe use VLC to transcode sound only and remux that version, hoping it will be of correct length ?

Now that I have more terrestial DVB-T MPEG2 and H.264 channels (including HD), I am expecting I might see more dropouts, so I want a workflow that can handle that.
