    I've found something really strange! The box does that error after installing a softcam app, oscam.

    I dunno if the problem is about configuration or about ram usage, but it shows after installing it.

    I'm trying to discover where the issue is.

    Yes it is possible that a plugin may create some issues, I've seen that more often with softcam apps.

    I believe I've solved the issue.

    Here's what I've done:

    I've done an accurate difference check between the working vu duo and the "defective" one. I've discovered that the first always had more than 20mb of free ram, instead the second one (with just one plugin more that the first vu) had 12-13mb of free ram.

    So I've downgraded oscam version, removed all the unused plugins and removed the usb pen I used for picons, epg and swap (in the first vu duo I use a CF card, that I can't use on the second vu because the hub hasn't a cf port): more than 25mb of free ram.

    After these "mods", the second vu didn't show anymore any kind of issue about signal or sid/pat error.

    I don't know why this happened, maybe the second vu has some problem with ram chips, I dunno...but in this way I've solved my issue (for now).

    Great, so it seems that you have sorted that out.
    So, basically it seems to be a nand flash chip issue, probably to many bad sectors, thus the storage capacities is lower than normal.
    Thank you for giving your solution.
