What NAS?
I found I had SMART errors and replaced drives, that helped my issues, but def. switch off the Mem Playback first.
There is a NAS Tester win tool as well to check your R/W speeds to NAS.
An 1812+...
No errors or anything in the NAS log, rough speed checks always around 100MB/Sec.
I can do very large copies off it no problem. I don't think the problem is the NAS, 'must surely be some very intermittent hardware issue.
The system will play music for 12+ hours no problem, then just stop, screen-freeze. (theater view) can't exit or anything. no errors.
It appears Windows has stalled, but since it's a player "appliance", no mouse/KB or such. it's hard to tell.
'had a mouse KB hooked up last evening, and of course it played all night no problem, still playing this morning.
I don't believe it's anything at all to do with MC.
I ordered some new RAM for the MB (Asus P8Z77-M) to try next. This particular player ran fine for at least 6 months, then since roughly a month ago I've gotten a few of these "freezes".
