I noticed this yesterday. While watching ESPN yesterday, Directv inserted a local commercial for ACO hardware (a Michigan hardware chain) and when the system tried to switch back to the national ESPN feed, the picture froze and I had to switch channels back and forth to fix it. I guess Directv is trying to roll out local insertion commercials but the software doesn't seem to be ready yet. Anyone else noticing this at all? I'm on software version 0x799.
