AU9-SL3 to WB68 to DirecTV R10's

[tbrandom]

Just installed an AU9-SL3 Dish.
Using 4 cables to a Zinwell MS6X8WB-Z (WB68)
Driving 3 DirecTV 300GB R10 TIVO Receivers (mine)
Get an outstanding signal on A, B, & C. (93-97)
But the next message says
A OK
B not detected
C not detected
Everything still works if I ignore this, but the controls are sluggish and the receivers occasionally lock up.
Do I have a switch or dish compatibility problem?
Don't want to give up my R10's.
Appreciate any guidance or recommendations.

A=101
B=119
C=110

The Slimline3 receives 99, 101 and 103, NOT 110 or 119 (the Slimline5 sees all 5). Your R10s are not capable of receiving 99 or 103 (they only receive MPEG2 signals). What you are seeing is probably normal. If there is a setting to have the receiver only recognize 101, that might speed things up a bit.
