Hello, good saturday!

I'm having issues with the decoder in subject and 128gb sdcard.
I decided to use a big card as hdd for recording (i dont like the added space of an external usb hdd or stick).
I used a 32gb (kingston canvas select plus) and all was ok. Swapped with a 128gb, same brand and model.
Decoder an access the memory, format it and seems to be ok with it (therefore my guess is that the memory controller is ok with SD-XC) but if i record something, the decoder freezes after some (random) while.

Ideas/suggestions?
I'm using openatv 7 image.

thank you in advance for any hint.
