I've replaced the 8GB USB stick with a 500GB SSD. Still the same problems (crash/freeze regularly)
I've also put in the 50/60Hz python fix.

One of the logs has this in it:
Code:
<   325.831> [eventData] EPG Cache is corrupt (eventData::~eventData), you should restart Enigma!
I've since deleted my epg.dat file. The other crash logs don't mention this

As I've said, the USB stick with the EPG data worked perfectly with Hades 018 for over a year.

One other different between my Hades018 and Viz 5.0.11 installation is I'm using Fallback tuner which is also configured to get the abm and epg from the server receiver.
Could this be the cause of my problems?
