how many impulses do you have on the system? I had 2000 on my Stadium and it began to lose its brains. Buttons stopped working, huge delays and lag, failing to boot properly.. Support relayed back that based on other reports, they wouldn't recommend going over 700 IRs. I'm not sure if that issue would also relate to a sizeable amount of .clone files as well.
after i removed 1500 impulses the lag and boot issues stopped.
No need to respond here. I saw that you were on FB.
