I'm getting a new tv(52LG70) that uses HDMI(my old one used DVI) and was wondering if there would be any loss of audio quality by connecting my PS3 and satellite receiver etc. via HDMI to my tv and then using an optical digital cable from my tv to my receiver.
My Marantz receiver isn't HDMI capable so this is my only option until I get a new receiver, which won't be for a while.

Use HDMI cable from the PS3, and from the sat receiver, to the tv for video.
Then run optical cables from PS3, and sat receiver, to the A/V receiver, instead of the tv.

The optical output on most tvs is for audio from local HD channels, that are received with an antenna. It's usually not meant to piggy-back like you were suggesting, although I've heard that a couple of tvs will allow it.
Samsung HL61A750 (LED DLP)            Onkyo TX-SR805
Oppo BDP-83 Blu ray                                  Polk Audio LSi9
Polk Audio LSiC                                  Sony SS-MB100H
SVS PC12-NSD (Sub)                       ...

You won't get the full benefit of some audio (HD Master Audio, for instance) over the optical connection, but you will get audio of no lesser quality than you have been getting.

To take full advantage of HD-MA, you'll need HDMI connection to your audio system, or a BD player with analog outs and the proper codecs built in.

That's a relief, that's what I was hoping. I really want the HD audio but will have to wait for a while, I just spent a large sum of money on the tv & PS3.

Thanks for the replies, it's much appreciated.

No problem! I'm in the same boat - much better picture, but still optical (SPDIF) quality sound. I suppose I'll get the itch to change that around Christmas time...gleem.

Oh, and enjoy that PS3. I've never been a gamer, but I bought the PS3 for BD, and a couple games for the family to play together. And we _love_ the media server connection, to let us view our photos on the TV. I even use the 'net connection to check TV listings, since the on-air listings are always wrong or incomplete.
