Hi brian,

Not sure if it will works for you, but you probably have some old components in the playback level. So we need information to debug, and seems that most of users are not able to provide them (not their fault) because needs to manipulate in command line.

If you can run with -vv (yes 2 v's) that you will have a better message (best if you run) open canola and then try playing on media. I think you can copy it and send using the email on the tablet (open gmail o browser or even this thread and copy here )
Select the test by dragging the stylus.. and hold down it to copy.

We are already looking after this... the fix is on application manager: canola2-fix

BR
