Some channels are not viewable using ceton proxy, but are in WMC

[Applegrcoug]

I am having trouble with cetonproxy showing some channels, one being the Pac-12 network. If I use the VLC trick, all I get is a network error that says it can't open the channel.

However, I can open and view this same channel in Windows Media Center and when I go the ceton device webpage to the channel that is tuned, it shows it is receiving the channel.

Channel 453 tuned in via WMC and working

Channel 818 tuned in via ceton proxy and working

Channel 453 tuned via ceton proxy, but NOT working

Any ideas what might be going on???

Thanks-
