Common TiVo HME Problems

Exception When Running Simulator

java.lang.ArrayIndexOutOfBoundsException: 0
at com.tivo.hme.sim.Simulator.main(Simulator.java:756)

You'll get this error immediately when trying to run the Simulator.  One cause: no active network interface on your machine.  (This happens to me when I'm working on my laptop and I forget to turn on WiFi.)

IP_ADD_MEMBERSHIP Failed

java.net.SocketException: IP_ADD_MEMBERSHIP failed (out of hardware filters?)

I get this occasionally when trying to start the Simulator.  A reboot fixes the problem for me.
