These are just some notes detailing some recent experimentation - hopefully some of you may find them useful. Probably all of this functionality is available with the custom firmware - but while the box is still in warranty not everybody may be ready to take the plunge...
While it is possible to remove the "ENC" flag from *.hmt files in linux using foxy running under mono it is quite a manual process - something like:
1. ftp into your Humax using FileZilla, or similar.
2. copy the hmts onto your local machine.
3. run foxy and then drag and drop each hmt in turn for conversion.
4. copy the hmts back using Filezilla again.
If you have a lot a files this can take a while, and so it would be nice to accomplish all of this with a single command. Here's how.
Step one:
Build yourself a command line foxy equivalent. It seems that it is only the bit at 0x3DC that needs to be updated to get your Humux to decrypt HD recordings for you, so:
touch prog.cpp
then open the file in a text editor and paste in:
---
---
save it, and compile with:
g++ prog.cpp -o Foxy_DC
If that works, you should be able to run it with:
./Foxy_DC <your_filename>
Step two:
It turns out you'll need another command line tool later too, so you may as well build that now:
touch split.cpp
and paste in:
---
---
And complie with:
g++ split.cpp -o splitter
This is a nasty hack to get the file names of your recordings into a more useful format.
Step three:
Automate pulling your hmts off of your box. You'll need a bash script for this, so:
touch ftp.sh
Then open the file with a text editor and paste in this lot:
---
---
You'll need to make this script executable on your system. You'll also need to modify the IP address of your box. The DIR can be up dated to 'My\ Video/series_name' if you want to run the script on a different directory.
Step 4
In whatever directory you have these files:
mkdir Archive
so you have somewhere to backup the unmodified hmts (just in case).
Step 5
./ftp.sh
Step 6
Check all your HD recordings are now ready to backup....
