Any chance you could upload one of them to Dropbox or GoogleDrive (....) so that other can have a look at the actual *.ts file?
Sorry - my confusion.
I just browsed past posts mentioning filezilla, and that you couldn't find the ntfs-3g package, so presumed you weren't using an ntfs drive directly.
I think I have fixed the issue, only time will tell. Th problems occur when playing them in in other devices and there hardware/software settings. I frst had this problem when playing them on my android box via Kodi. When using Kodi you need to select under videos settings the following:
select =Allow hardware acceleration amcodec
de-select - allow hardware acceleration- Mediacodec (surface)
de -select - allow hardware acceleration - Meidacodec
So far the HD .TS recordings from my ET8500 works on my media player.
As for my laptop with Vlc I'm sure it has to be similar settings.
