Just an update - I've scanned through the .HJM files from my friend's HDR1100S and unfortunately the recordings are all from HD channels - therefore encrypted, and only playable on her machine.
Looks like the only option is to get out the hot air gun, or send it off to one of the repair services.
Has anyone here had good (or bad) experiences with these, and any recommendations?

It appears that both sd and hd videos are encrypted and no amount of digging has found how to decrypt them.
Make sure the contacts on the sata connector on the motherboard and on the hd are clean. Spray them with electrical cleaner. I found the connector to be a bit flimsy.
I have previously fixed TV boards and computer motherboards by putting them in the oven for a short time. Also hot air might just do the trick.

In my view the explanation of "resets the hard drive overload in the humax chip" makes no sense but for several people the heat gun does seem to have been beneficial.

Just as an update, having decided that the files could not be made readable on another system, we took the chance on the heat gun technique.
As there are not many details on how to do this about, here's my method:
1. Remove the circuit board from the case - just open the top by unscrewing the middle screw at the back, and ease open the five grey plastic tabs holding the top on from underneath, remove the HDD by taking the four screws out of the bottom, and the bracket on the top, unplug the Wi=Fi card from the PCB, remove remaining three scews retaining the PCB, and lift out.
2 Remove the Heatsink by unscrewing the three screws on the top and gently twisting off. Clean the (probably dried-out) heat conducting compound from the CPU Chip and the heatsink (Alcohol is good for this).
3. Place the board face-up on a non-conductive, heat resistant surface, and heat the green CPU from above for about 30 seconds - I used a standard paint-stripper hot air gun set at LOW (375 Degrees Celsius) held about 2 in (5cm) above the CPU pointing down.
4. Let it cool completely, then re-assemble the heatsink applying a small blob of heatsink compound - ensure that the screw mounts are parallel with the ridges on the heatsink before assembling, as they can foul and reduce the flexing action of the springs in the screws.
5. Re-assemble the HDR-1100S in reverse order, connect-up and switch on with fingers crossed.It ran a 12-hour continuous playback test with no problems, though the heatsink temperature rose to 70 degrees Celsius - rather close to the chip rating of 85 degrees Celsius. Humax should really have designed better airflow - perhaps slots above the heatsing to allow heat to escape.
Will try to report how long it lasts.....Attachments
