So 5 at the same time? and all though the day? Was this for testing or do you generally record that much?
Same as me with my tests, 5 or 6 seems to push it over the edge...I had 5 sd recordings through the night, no reboots, added a 6th in the morning (hd) and rebooted straight away....and had 3 sd recordings running all through last night and no reboots.....for me this is excessive as i only record the odd film here and there...so this image is working 'normally' for me but i know it's not perfect as per the tests i have done...but you have to admit that 4.2 is much more stable...the others i was getting reboots regularly even without recording..Let us know how you get on with Apollo19 but i think you will be back to 4.2
