Hi SJ :
Strange this problem of not finding the mpeg-4 files... we indeed updated the LMS (scanner) so this maybe related, could you please send one or 2 of your files so we can add to the test list? (Private message me for my email)

About the freezing, I haven't received bugs about that yet, but if you can find a way.
but it really seems even more that there's something happening now and then in the installation (not for everyone) like corrupted packages being accepted as good by the application installer resulting on broken installations... that leads to problems.

So, did you install other applications before installing canola on your last reflash ?
