Resultant mkv is VFR?

[doobre]

Hi there, just wondering if anyone has come across this weird output issue.
When ripping a BD of Sheryl Crow - Soundstage the output from MakeMkv shows in mediainfo as variable frame rate and handbrake refuses to encode it.
VFR is not a valid format in BD terms so I doubt that a commercially produced disk would be using such a 'trick'.
When the makemkv output is played back in VLC and PowerDVD12, the video is playing at double speed compared to the audio.
As I said weird, never come across something like this before, and I have copied many BD's.
cheers CD

What happens if you make a decrypted backup of the disc (icon of yellow folder with green arrow on the first screen in MakeMKV) and then use MKVToolNix on the backup to create a .mkv file?

Hi there, thanks for the reply.

I got around the problem by ripping with handbrake.
But out of interest I will follow your suggestion and get back here.
Cheers CD

Hey dcoke22
That sorted it out, but think it might be of interest to the dev's to understand what went 'wrong'..
here's the mediainfo fot the backup .m2ts stream file.
cheers for the suggestion.
