Just so you know you're not alone I have the same issue on my MiracleBox Premium Twin+ Plus with version 030. Fresh install.
Couldn't use 027, 028 or 029 as tuning didn't work (see other thread).
Was very happy that 030 fixed that issue but now cannot record anything.
Also got this using OpenATV which is why I came back to try 030. If it's on both systems is that a kernel problem?
Back using 4.1.016 which seems pretty stable and it has never missed a recording, shame about no plugins though.
It must be a nightmare trying to keep this software working on so many different versions of hardware. Perhaps they need more beta testers with all sorts of machines? I'd be happy to help but I only have one box which is in constant use.
