Unusual defect related to .m2ts files

*.m2ts is supported but it may be a bad encode,dvr/dvb recording … etc

Use MKVToolnix to Remux the file (takes a couple of minutes with no quality loss)

I always use this program as the 1st way to fix a file.

The new file will be a *.mkv  … give it a try, as ive had pretty good success with it
