tuner configuration

[kryton]

My Xtrend et8000 currently has 2 x satellite tuners.
When i bought it i seem to recall there was certain tuner configurations that the Xtrend manual said not to use.
Ive since lost the manual so im wondering would it be possable to have 2 cable tuners and 1 sat tuner?
Ive noticed cable tuners are half price from the sponsor at the moment so now would be the time to buy :-)

Thanks.

ET8000 manual.... http://www.world-of-satellite.com/showthread.php?45844-Xtrend-ET8000-User-Manual&p=356672&viewfull=1#post356672

It's the ET10K which has the weird and wonderful tuner combination restrictions. (They share the same manual.)

2x DVB-C & 1x Satellite is fine to use.
