Well first off what about the VMCE-2008 "TV-Pack"?!
It's not like it actually supports anything useful, such as DVB "C" or "S", just that same tired and utter useless pile of crap "T". Which might be fine for those of you in the UK (FreeView), or in the US where almost anyone has access to a Digital Terrestrial Transmission (ABC, CBS, FOX & NBC), but "T" just isn't worth the time & expense for those who live somewhere else. As those channels are usually carried by the local Cable Co. or say over the Astra Satellite Network. Upshot being limited by about 15 Channels to 15.000+ from Geostationary you do the math! More might not =/= better, but I happen to enjoy having a choice!
Now as for MediaPortal....
How the heck can you even recommend this to anyone? I never seen a more retched Program since (perhaps the early-ish days of Vista?). But like Vista MediaPortal is even more flaky yeah unlike the above, it does support DVB-S /*S2 -C and -T with Common Interface for Conditional Access Modules. Something that Microsoft should have ALSO HAD BY NOW!!!!
But what's the point of it when it takes nah-on forever to change channels and hope that such messages actually reach the CAM in order to decode the properly??
If your really serious about having an HTPC there is really only One answer, and that would be Linux! Or which I'd recommend Kaus Schmidingers' VDR (Video Disk Recorder), Basicly it's the same OS that is used in the reassuringly expensive Reelbox, and unlike the above & above. It works with every DVB Standard out there i.e. S/S2 C and T and it can do HD as well.
The only downside is that you have to be careful which hardware you try to install but if you stick to OEMs like KNC1, or TechnoTrend you'll be safe.
*I think MP has support for DVB-S2 as well but IIRC it eats away at your DiSEqC Table, Since I like useing DiSEqC for (13.0e, 19.2e, 23.5e & 28.2e/28.5e) , I don't take to kind to this "fix"...
That said MP is ~just~ a bit more usable then XP/V/7-MCE. Sadly just not as usable as any of the Linux based stuff from which MP hails from....
