Thanks for the heads up. PBS is the way to go. Are you out in the woods or something? I'm off lower Newtown / EAST ave. and I lost WLIW 21 intermittently in the past, then tried the HD channel and there it was. Juggled my DVR recording sched in the nick of time to record my favorites. After awhile i started thinking WLIW 21 was to blame. Maybe was. I had a similar problem a couple of years ago, it would freeze and bump along.
