Tonypbx's post emphasises the need for an idiots guide for real newbies (like me) to Raydon's software
here , as, like me, it seems that he does not fully understand what's what.
It's Raydon's modified S/W that needs to be installed on the HDR. There is a link to V4 of this in the second post of the one I have just linked you to.
As I understand it, AV2HDR runs on the PC (not the HDR) to convert various different video formats that required by the HDR then copy them to the HDR to play them. (I havn't done this yet).
You don't need filezilla on the PC to access your HDR from a Windows PC, you can just use Windows Explorer, or Network.
As you might be able to deduce from my other post, I don't know what's what either, but the above is what I have picked up over the last few days.
Foxsat latest firmware is Humax v1.00.17, but Raydon's S/W is built on top of this, and replaces it.
