not sure how this correlated, but facing my '26.5 hours problem' i found next:

running on plain ts-file is ok:
./ffmpeg -copyts -i 27hours.ts -c copy -f null -

but if this ts-file is wrapped in m3u8, any of this commands:
./ffmpeg  -i 27hours.m3u8 -c copy -f null -
./ffmpeg -copyts -i 27hours.m3u8 -c copy -f null -

fails with:
[mpegts @ 0x2cf6680] DTS 788 < 8589931780 out of order
[hls @ 0x2cf3400] DTS 788 < 8589931780 out of order

[null @ 0x2e28980] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 8589805780 >= -121612


$ cat 27hours.m3u8

ps: ffmpeg = git-master + patch from this mail
