Hey, John - Royal Oak, right?
I haven't noticed any problems at all with the Detroit OTA's except the aforementioned problem with 56 (which has been fixed). I only watched a couple minutes of channel 4 on Sunday (Shrek), and didn't see any problems(looked great, actually). Last night I watched ch 7 for an hour (8-9pm, Extreme Makeover: Home Edition) -- again, no black screen, no issues. I'm tuning in to ch50 at nine tonight to watch Veronica Mars (I'll be flipping to MSU/Duke on ESPN at commercials). If you watch either of those, let me know if you see any problems. Also, might watch the Michigan game at 7 on ESPN, but I'm not married to it. If you're planning on watching something specific at 8 (or any other time today), let me know & I'll check it out.
