Videos I've saved from my old cell phones are coming up as .plt and .blt file formats. They used to be 3g2 format playable as a .mov on QuickTime. I never converted them to anything else but for some reason they are now in these formats.
If I prompt the tablet to open the .blt files as images, I get a thumbnail for the associated video. The same cannot be said when I prompt the tablet to open the .plt file as a video. It simply tells me the video cannot be played.
