I am new to pitivi so this is baulking me immediately.
I have some video files saved from a video recorder that have a TS extension.
VLC plays fine with no problems, Movie Player states software to play file is missing, if I cancel the option to search for a plugin it then plays it fine anyway.
pitivi tells me 'an error occured while importing'.
This appears to be a codec problem, there are so many gstreamer plug ins available and most appear to be installed on my ubuntu system.
Is there anything else I can try.
