Hi Fidelio,
Not sure about which HDTV card, but wanted to share someting anyway, I had a Hauppauge PVR150 (x26) for my Vista Home Premium MCE.
My card burned through, I think, could not receive any channnels one day, tried everything, but gave up. Left it for about 6 months but I recently upgraded Nero to Version 9 and JRiver to MC13 and I thought I'd give watching TV on my PC another go, but did not want to spend a fortune on a new TV-card.
I came across the AverTV Super 007. TV+FM, remote control included (direct cable to outlet on back of tv card). Tried to install today, no luck in Vista yet with the AVERTV 6 program that came with it. Installed upgrade from their website, no luck, tried Nero 9 live, all no luck. Then I tried MC13. It scanned my analog channels no problem, something I never managed with my old Hauppauge card (which I used in MCE). Tagging/renaming channels is easy in MC13 and, and this I thought was funny, I installed UUIRT (USB UIRT) remote plug-in from the JRiver website as it occurred to me I still had my old USB remote from the Hauppauge Card, and guess what, it works! I have volume control, channels up and down, even the record button. Check out the AverTV website in your country to see if they have a model that works for HDTV. My analog card cost Euro 34.
I did a quick Google and I saw two interesting candidates for your wishes:
External:
AverMedia AverTV DVB-T Volar X [A815] for under Euro 30. This plays digital HD TV only, has a remote and is MCE compatible. This model plays MPEG2 HD channels and H.264 HD channels, it records as .mpg and .mp4 and has timeshift. Supports both EPG and DVB-T. I've not had experience with external TV card via USB, so I'll leave the reviews to others.
Internal:
Asus comes with the My Cinema-EHD2-100/PT/FM/AV/RC Dual Hybrid TV CARD: PCI-Express x1 interface; simultanious digital DVB-T and Analog (PAL) playback and recording; Mpeg2 encoder; Picture Beside Picture (PBP) funcationality; FM Radio. Not sure what the price is.
Both DVB-T, not DVB-S, though.
For DVB-S
FireDTV: see this page:

Hope this helps. Good luck on finding the right card.
