Once saving a file in Openshot it flags 'Invavlid' when tryimg to repopen it

[Chris J Berry]

Hi There!
I dual boot a system running Mint 18 64 bit (updated daily) and Windows 10 64 bit(update turned off because of the risk of Grub error- windows used only to burn DVDs in Nero, as cannot find reliable burner on Linux yet) I have installed 64 bit Openshot version for editing the films, and regularly update Mint 18 each day before working on my comp. If I edit and export the films during the same session no probs-- Invalid flagged only on new session.

Bug_
I edited adverts out of a film I had recorded saved as a .TS file, and then saved the file as DVD Pal before exporting it. I went back to it to export another file clicking on the .osp file the next day and the file was opened in Openshot but flagged as Invalid -- no graphic displayed but audio.ts was playing.

I re-edited the file and saved the project in Openshot as before, both as 'saved project' and 'saved project as' before exporting the file as a 'DVD Pal'/'DV/DVD Pal'. I clicked on the .osp file and it opened audio.ts and video.ts files in Openshot. The next day I went in and clicked on the .osp in question, but this time it flagged the 'invalid' but displayed the file on the time-line as before playing the audio.ts file, My computer is new though I am not a streamer or gamer, but wanted a decent unit to run graphics and audio files with a Asus M/B with onboard codecs and graphics.
Hope I have given clear, sufficient info... With thanks Chris... Truro... Cornwall. UK.
