Tvheadend

Hi

I need at least two DVB-C Tuners so i can stream/watch two different channels at the same time through TVheadend to Kodi. I need the cheapest solution..

First: does HDHomerun EXPAND

works with tvheadend (is there a driver)?

Second: would it be cheaper to buy two dvc-c tuners on either PCI or USB? if so can you recommend any model? the tuners I can find will cost nearly the same for two tuners as the price for Hdhomerun Expand where i get 4 tuners.

Please advice.. :-)

Best Reagards, Steffen.
