dvd folders not playing

[fuzzweed]

I'm getting kicked back to the menu screen when I try and play a video_ts folder (showing as dvd extension) from the video library. it's also happening with iso files. I think this started with the change from v1.3 to v1.4 but cant be sure.
getting this in the logs

found the problem. i'd made some changes to the dvd key mapping file (following another thread) that had caused the error.
