[NMJ v1] Problem with MKVMerge v3.5.0

[Netmask]

EDIT: Just realised I posted this in the wrong forum - can it be moved to the correct area?


On my Popcorn C200 running the latest firmware this file presented intermittent problems like, navigation resulted on resume no video no subtitles just audio. Difficulty in displaying subs at all.

I checked the subs and they were error free srt type, ansi encoding.

I then examined v5.3.0 a little closer and noticed that it was possible to compress the srt subs - maybe it was there in earlier version but I didn't notice nor have any problems. So to be on the safe side I set the compression on each track, audio, video and subtitles to None and set the Forced flag on each track as well for good measure. The resulting corrected file plays with subs and navigation intact. MediaInfo details follows.

Anyway the file now works - so I am happy as the original recorded audio was badly dynamically compressed resulting in background noises coming up between words that subtitles were necessary to help with the dialog Intelligibility.
