@framedtoo - The reason i suggest going private for a while is mainly because there are major DRM issues at play here - i suspect the reason there is a key preventing us from falshing the box is because the BBC/SKY/ITV etc will not want a bunch of hackers taking their HD recordings off the box etc and the uploading them to tvtorrents.com etc.........
If we publicise out work like this then I suppect we will find a OTA update to the loader come out while were not looking which makes it 10x more difficut do what we are trying!
The other issue is that reverse enginearing the hdf and moding the software is illegal in the UK without expressed authorisation from whoever wrote it (i.e. HUMAX)
I think you're missing the point a bit here. You can already transfer encrypted HD video off the box via FTP, so where is the increased risk ? There are no 'in the clear' recordings stored anywhere on the hard disk, unless you put your own content on there. Every 'native' recording is encrypted with a key which is unique to that particular box, so you couldn't even play it on another T2.The only illegal thing is using the Windows HDF tool to remove the encryption of the hdf file. From that point on its fine.
My main concern is that Humax may end up being forced by other companies to increase the encryption of the file system in the HDF file to prevent us from doing this if they consider it to be a risk to files you record onto the hard drive from HD channels which are encrypted.
