Quite a range of equipment !
I have a Zgemma H9 Twin which I have just converted from ext3 to ext4 using the menu screen instructions. Will become my spare receiver. My Vuplus seems to have no 'convert ext3 to ext4' instruction. I have just saved the HDD contents to external memory before trying out initializing, but there was no mention of ext4. Looking through google there may be a way of achieving ext4 using the image (?). I use a TNT card in a French receiver, can it be used in a Vuplus Duo ? Perhaps i need to start several more threads......
