Thanks again AbuGenuine Sony DVB-T Tuner for PlayTV | eBay
Sorry for late reply, but hopefully you got same as above. Just for info, the recording is done by muxes/transponders, not channels. Saorview only uses two muxes per area, so you can record all the channels. Not just two.
Wow installing a second tuner is a no brainer so in that case as it appears with the two muxes, one will have great flexibility for recording and watching saorview all at once, Thanks for the tuner link also
