SamyGO

Interesting topic. However, you mention C version, which is in fact unsupported by SamyGO and FW was not disassembled by now.
Regarding two points - you can check the skipping function when playing TS stream on your own..? (sample stream can be created or recorded by TV..?).
And for B version it applies, it would be possible to send keystrokes from RC to the net (via hack).
