I thought the original Ver1.0 1000S was immune from this....
Symptoms:
Flaky operation (file format not supported) followed by no operation (can't pause live TV etc).
Tried:
Replacing HDD with numerous spares (all "in stock" here at home). Says it's formatting - but on inspection after powering off, there is nothing done to the HDD.
Leave it switched off for a while. This causes it to come back to life. For a bit - after which back to square one.
Bin job? I bought it in Jan 13, so it hasn't done too badly...
