Just wanted to follow up on my Roku not recognizing my SD card...
Over and over Roku kept insisting it was my fault, I didn't insert the card correctly, etc., etc.
Then one day my Roku announced it had a major upgrade, which took quite a while and ended up putting itself into an endless loop of a video showing me all the cool new features, most of which I didn't want. I had to unplug the box to get it to stop and reset.
And guess what? That SD card that nobody could explain why wasn't recognized... now was recognized. My my.
