- The analog module is not fully supported yet.
  The MSP3400 module will have to be extended to handle then audio and 
  video switching for the module.
  If you want sound you will have to remove the module for now.
	
- If you do not receive any packets over the dvb0 device the reason could 
  be the rp_filter. 
  Check if your distribution enables this or disable it with:

  "echo 0 > /proc/sys/net/ipv4/conf/dvb0/rp_filter"

  This disables source validation by reversed path lookup.
