I found this info on playing video files on the MagicTV. You can basically convert anything and then play it on the MagicTV. A work around until they provide more format support.

I haven't tried it yet, but from the manual it seems that the file is copied onto the internal HDD not played from the USB. I am wondering whether you can later pull the file back off the HDD onto the USB HDD?

If so is this an opening where with some internal code work, it might be possible to do the same with the other files on the drive? Just a thought.

Anyone used Super for this?
