Hi, I just got foxtel working with my HTPC! It took some doing but I finally got it going. I also have the DNTV Live Hybrid S2 tuner card and it's fantastic! I am able to record from foxtel plus 2 FTA channels all at the same time!
With regards to the EPG, I used FreeEPG* with the platinum package. Keep in mind that this does not have the FTA channels listed. You will need to do some work to get those in the guide along with the Foxtel channels.
You must also be aware that MCE by default will only see one side of your card, either digital or analogue not both.
Follow Broadstar's thread to enable both:
Get Most Cards To Work In Mce
There are quite a few guides here on how to get it going. The ones which helped me the most are:
Digital and Analog TV (Guide)
MCE - Foxtel / PAY TV Guide
DTV and Analog TV Works (TOGETHER)
Good luck!
