I like the idea that v3.0b installs to a separate directory, I will try that tonight.
I have turned off the Network feature and the application seems to be running pretty well for the last 36 hours. I am also getting a new cable modem tomorrow, DOCSIS 3.0 with (supposedly) up to 50 Mbps, and perhaps the new computer next week. I will try the Network feature again after that and see if things improve.
Thanks for all the help with this fascinating toy!
EMA: depends on the problems! If they are minor (which they are) then V3.0 has much more performance, is faster and decodes more traffic.
