Well, I've tried to switch between those two channels and had no problem
on my system (two budget cards).

My setup is similar to your's (all cards connected to a single multi
switch) except that I lack the third LNB for 28.2E.

My diseqc.conf looks like that:

	# Optimized for full DiSEqC:

	S19.2E  11700 V  9750  [E0 10 38 F0]
	S19.2E  99999 V 10600  [E0 10 38 F1]
	S19.2E  11700 H  9750  [E0 10 38 F2]
	S19.2E  99999 H 10600  [E0 10 38 F3]

	S13.0E  11700 V  9750  [E0 10 38 F4]
	S13.0E  99999 V 10600  [E0 10 38 F5]
	S13.0E  11700 H  9750  [E0 10 38 F6]
	S13.0E  99999 H 10600  [E0 10 38 F7]

I think, your diseqc.conf should look like that:

	# Optimized for full DiSEqC:

	S19.2E  11700 V  9750  [E0 10 38 F0]
	S19.2E  99999 V 10600  [E0 10 38 F1]
	S19.2E  11700 H  9750  [E0 10 38 F2]
	S19.2E  99999 H 10600  [E0 10 38 F3]

	S13.0E  11700 V  9750  [E0 10 38 F4]
	S13.0E  99999 V 10600  [E0 10 38 F5]
	S13.0E  11700 H  9750  [E0 10 38 F6]
	S13.0E  99999 H 10600  [E0 10 38 F7]

	S28.2E  11700 V  9750  [E0 10 38 F8]
	S28.2E  99999 V 10600  [E0 10 38 F9]
	S28.2E  11700 H  9750  [E0 10 38 FA]
	S28.2E  99999 H 10600  [E0 10 38 FB]

As far as I recall, selecting among more than 8 LNB connections requires
 the use of full DiSEqC, as only 8 LNB connections can be addressed by
supply voltage (vV), 22 kHz tone (tT) and tone bursting (AB) (pre DiSEqC
1.0).

In your diseqc.conf, you mix pre DiSEqC 1.0 with DiSEqC 1.0 in a similar
way as provided in the stock diseqc.conf below '# Full DiSEqC
sequence:'. This should not be a problem in general as the standard
says, that the switch should prefer a properly received full DiSEqC
message over mini DiSEqC signalling but it may interfere if there is a
transmission error in the full DiSEqC message.

Moreover some switches seem to store the decision whether a client uses
 mini or full DiSEqC until the switch port sees a power cycle. This
might explain why reloading the driver cures the problem.

Bye.
