DVD Ripper error during convert

[rswiders]

I am trying to convert some movies I copied to disk ISO files. After starting a rip (from dvd to m2ts format), it just stops with an error.

This has happened on 3 movies so far.

The error i get is:
error: Work 1 failed, Error = graph not_suitable_connected_filter graph(0) - pinName:video frame

I did further testing on this rip issue.

I am able to rip to a different container format (mkv) successfully with the original files. After that completes, I am able to use convert to change it back to the desired format (mkv -> m2ts).
