Will my present setup produce True HD lossless Audio ?

[rox addict]

Okay I'm a newbie and a poster suggest that my question be posted here so here goes. I just purchased a Sony BDP-S300 and I'm finding out that it does not decode True HD Lossless audio or it does ? ( I'm confused.) I have a Yamaha HTR-5740 6.1 AVR thats only 2 years old but does not have any HDMI inputs. I want True HD lossless audio and was wondering if I traded in my Sony BDP-S 300 for a Panasonic DMPBD30 could I then get True HD lossless sound using my present Yamaha Receiver ? I am just about to bite the bullet and purchas a new Yamaha RX-V663BL receiver to get True HD audio. Thats another $500 but man I've come this far to finish my AV room so I just might do it. If it is possible to get True HD lossless audio through my multichannel outputs with the Panny BD then I will go that route and thats just a $50 difference. Hope someone can help me and I'm so glad I found this site
