AVI files are displayed as M2TS files when viewed via S580 using Mezzmo.

Mezzmo device settings - Sony BDP (PAL)

An AVI file on a USB stick connected to the S580 is shown as an AVI file and plays correctly. The same AVI file via Mezzmo is displayed as a M2TS file and won't play 'file/data corrupt'.

Is seems as if the AVI file is detected as an M2TS file by Mezzmo - why?

Any assistance appreciated.
