I bought this unit about 3 or 4 weeks ago. From the beginning it said YouTube is not supported on this device. I've seen a lot of other models with the same issues and perhaps they're being fixed perhaps or not. But I would like an update on this particular model when this will be fixed. We phoned in gave them our Mac address. Told him about the issue. We're told they'd get back to us and we've heard crickets.
We were going to return it and support convinced us that this would be a non-issue.
BTY I also have a classic and it works just fine.
