Both TV and video card will have to be HDPC complaint... and I would recommend that both have HDMI conectivity.

Also, it would be best if the HDTV was 1080p, although 720p/1080i will still look great, it is best at 1080p.

Actually as far as pc drives and video cards are concerned, you don't need one with an HDMI port. An hdcp compliant video card and monitor with DVI is fine. Video cards don't carry and audio signal anyway, so it somewhat useless to have one HDMI.

will you get lossless audio if you connect the pc audio outputs to a receiver?

That's a good question. Quite honestly I don't really know how one can listen to lossless audio in its full form (not downsampled) on the pc. At least not yet anyway.

I know that you can get a sound card with a toslink (optical) input and listen to a down rezzed version of LPCM 5.1, but to be able to listen to high bit rate lossless audio, that I don't know about right now.

Doesn't HDMI carry the video and audio digitally?

I'm just guessing here, but the HDMI must be taking the audio from the drive at some point - just as any other Blu-ray playback device would... no?

The problem is that in pc's obviously the video cards have the HDMI inputs, and I don't know of any video cards that double as sound cards. Maybe from now on they will be designed to carry both streams, but up until now I didn't know of any cards that did that.

No idea really.

I'm just spoiled I suppose... HDMI port on the side of this laptop.
Don't know if it is part of the video card or just another port on the main board that gets video from video and audio from audio - or whatever.

I know it works!

I know HDMI is the preferred connection for HD video & audio playback, right?

See, on a laptop it's different. Everything is coming from the main board, meaning that both the audio and video chip sets are on the main pcb itself. Now, some higher end laptops have dedicated video cards, BUT the HDMI port is still attached to the main pcb. In desktops you obviously have to get a video card in order to have HDMI input. I don't know of any OEM desktop motherboards that have HDMI port soldered on them.

This laptop does have a nVidia 7600 GT dedicated card... I believe.
I know it is not integrated video, never opened the case though.

This very well could be on a card.

EDIT: PCI?

Not exactly. The PC implementation is different than that used by CE devices. Even if the software player can "decode" lossless audio, there are no provisions for outputting such a signal digitally. The audio doesn't come out fo the drive... only data does. Then the software player has to decrypt that data, then demux it into video and audio streams.

Graphics cards with an HDMI output either have two ways of outputting audio: either they provide a connector for getting Toslink digital output from a soundcard or motherboard, or they have their own audio chipset. If they use their own audio chipset, in theory they could support lossless audio, but the audio is a secondary consideration to graphics card manufacturers, and as far as I know, none of them have announced the inclusion of an audio chipset with that capability.
