0. Please unplug the power cord of the MTV3200D, leave it for a day then retry. I recommend you take it to Magic TV office to get it repaired.
1. Please upgrade to latest beta firmware, and make sure both Magic TV are connected to the router (or switch) using network cable. Yes, MTV1000 can be used as a channel sharing client.
2. No - different CPU.

MTV3300D has dual tuner, component output, optical output, coaxial output, front panel, faster CPU and Gigabit Ethernet. Simultaneous HDMI / Component / Composite video output.
MTV1000 has a single tuner, is physically smaller, CPU is slower, and none of the above features. Its external power supply also outputs lower current. MTV1000 cannot output HDMI and composite video simultaneously.
