Receivers that work well with symbol rates above 30,000

[Cnut]

Do any of you have receivers that work well with symbol rates above 30,000? There was a 16APSK feed of hockey Saturday, with a symbol rate of 34284. I had no trouble scannning in all six channels in this MUX. It played well for a while, but then started to have color distortions from time-to-time. I was using a Manhattan 1997, which I have blind scanned a lot with over the time I've had it, so it may be wearing out.

What receivers do you recommend for those high symbol rates in 16APSK feeds?

thanks for any help you guys can offer
