Comment (by barsnick):

 Since I haven't seen the requested sample yet, I have added one which
 cannot be remuxed from MPEG-TS to Matroska, neither with "{{{-fflags
 +genpts}}}" nor without. Note that if you restrict the ffmpeg command to
 "{{{-t 10.4}}}", it will at least work upto that point. (I have shortened
 the sample just so long that it actually exposes the problem.)

 The sample is the beginning of an MPEG-TS file (shortened using dd)
 created with
 {{{
 ffmpeg -i http://... -c copy output.ts
 }}}
