Thanks for your very informative post.
Now I feel like such a nob!!
The BRP and TVxb process is working fine, and generating the appropiate files, which I have checked for valid info etc. No issues here.
The ISS stuff is also working fine and I can access the NATIVE files and guide.bin as advertised.
Keepkey installed and operational.
The only issue seems to be some nobhead

with admin rights to my pc has been deleting guide.bin manually and waiting to see if it get regenerated during the guide download process from MCE which doesn't happen, as you have so clearly explained.
I will try again later
without first deleting guide.bin. I have a warm feeling things will be different.
Thanks once again, I'll keep you posted.
