Hi Guys.

I have a question that I've haven't been able to find the information answer from a reliable source. What I want to build is a dvb-t based htpc. I've almost settled on media portal due to its ability to record multiple channels from one multiplex.
My question is with reference to support for multiple dvb-t devices. I see in XP pro, multiple dvb-t adapters are not supported, but they are in MCE 2005. Does windows Vista premium support both

1 - multiple dvb-t devices
2 - recording multiple channels from one multiplex?

the page with this information did not list Vista.

I'm not against using mythtv for this as an alternative, but, I also want the hardware acceleration of the H.264 codec, which I am not aware of being achievable under linux.

I'll be buying a new processor, motherboard, ram and graphics card for this, so the oem version of vista premium is not too much of an additional cost - assuming it allows doing this. Hopefully, other people here would have already done this..

with Media Portal server you can record multiple channels per tuner as long as they're from the same transponder.

allstarnz: with Media Portal server you can record multiple channels per tuner as long as they're from the same transponder. 

Which is why I want to know if multiple dvb-t devices are supported under vista premium. I intend to use multiple dvb-t devices(initially 2, perhaps 3 if anything interesting gets added to the 3rd mux) to allow all watched channels (tv1, 2 and 3) to be recorded simultaneously if needed.

There was 1 web site that mentioned that multiple dvb-t tuners are only supported under mce2005, specifically, it stated that multiple dvb-t devices was not supported under xp pro. This same website did not mention any Vista os at all. I'm not sure about the validity of this information, so, I want to know if anyone here has already set this up. It is possable that the information was just posting old information, but, I can't find it again, so I'm asking here.

Dolsen,  I think those references are in relation to what MCE is capable of supporting rather than the operating system. I have an HVR4000 PCI card (which has a DVB-T tuner) in my Windows XP based TV server. I also have an HVR900 USB DVB-T tuner and Media Portal quite happily accepts both the HVR4000 card and the HVR900 providing two DVB-T sources. I have never tried two DVB-T PCI cards, but I see no reason why they would not work using Media Portal.
Cheers Mike

As above, those are the limitations of Windows Media Centre which is just plain useless when it comes to NZ freeview playing and flexibility.

I think MythTV, GBPVR and Mediaportal all support those features, but im not sure.

Ive got 2 ASUS P7131 Hybrids and a PVR150 in my Mediaportal comp.  Ive had it recording 6 channels at once before so you can definately have multipule ones - just expect to have your hard drive going like crazy :D..
