The situation is very similar to the Toppy except the usb transfers
_are_ reliable and about twice as fast if turbo mode is enabled (which
disables the remote for the duration).
The only 'Gotcha' with this method being the invalid characters such
as ":" and "/" which can appear in the file names (you need to rename
any such files to eliminate the invalid characters _before_ starting
the transfer to a windows PC 'cos you only find out _after_ the
transfer of the offending file completes with a cryptic error message
and no file transfer to show for your pain).
Using USB is ok when only a few hour's worth of program material is
involved (an hour's worth takes about 15 minutes or so to transfer - a
piss poor transfer rate compared to what you see when using an
external usb hard drive with a PC where an hour's worth might transfer
in as little as a minute's time).
If you want to transfer a large chunk of your recordings, it's much
better to pull the drive and attach it to the PC (directly via a spare
IDE port is the fastest but even using an IDE to USB2 adapter will be
a good 10 to 15 times faster than the Toppy's own USB link - probably
20 to 30 times quicker than over the Humax's USB link).
The Filesystem might be based on a Linux or BSD FS or an entirey
proprietry one optimised for best streaming/minimum cpu overhead
performance[1] (not necessarily proprietry to explicitly stop users
from copying the recordings via a direct attachment to their PC).
For Toppy users, there's a little utility for dealing with this
situation (direct attachment of the HDD to a PC) called "TopfHDRW".
I'm pretty sure an equivilent exists for Humax users but I can't say
without googling for the info the OP can google for himself. Hint: for
the OP, it _will_ be worth googling for such a utility if you're going
to pull the HDD out of the PVR and attach it more directly to a PC.
[1] I believe the Toppy was built around the same reference design as
the Humax. From the relative performance (abysmal lack of in _both_
cases) of USB transfer speeds, it looks as though the Toppy uses a
more powerful CPU than the Humax (and, judging from the more
successful firmware upgrades and the ability to run TAPs, a larger
helping of ram).
The USB performance issues are a supreme exemplar of the shiteness of
Intel's spawn of the devil USB interface designed to soak up CPU
cycles for so little return (adding yet another pressure point to
drive the sales of newer and more expensive CPUs).
