My HDR 1 crashed at about 20:15 tonight and I've had to remotely power cycle it to get it back.
My HDR 2 crashed earlier in the week, twice in the same day, and I didn't bother powering it on again. It does this periodically - this time after a Firmware Loader upgrade (which I thought may have made it better, but probably hasn't) and 3-4 months of fairly stable operation.
My HDR 3 crashed, but rebooted itself, at 8:27 this morning.
My HD froze yesterday - it never does this and I can't tell what state it's in at the moment. Haven't got/don't need remote mains on that one.
Remote HDR (but currently local!) crashed on Fri. whilst left in pause during chase play for 3 hours. It's done this before and I should know better.
