During the week end I tested the openvix image on my decoder, and as one year before there is a problem with the external NTFS usb disk.
As you know the SE version doesn't have internal interface for the disk so you have to connect an external disk. I use a normal 500Gb HD with usb 2.0.
The filesystem is not recognized 'out of the box' you have to install kernel module and utilities , but when your disk is recognized, you will have trouble at boot ...
so you detach your disk from usb plug during boot and then you have to connect again when the system will be up, in the 90% of the cases the system freeze and you have the VIX logo that will turn forever.

What i mean is , in my opinion is quite normal to have an usb hdd connected to the decoder and quite normal that the fs is ntfs ( compatible with 99% of the pc on this galaxy)
