Hi I just bought a Panasonic PD30 which has great sound (it weighs a ton which must be all those speakers in it) so I am a bit loathe to spend another £300 - £500 quid on an AV receiver and 5/6 speakers . So my idea is to buy an AV receiver and rear speakers plus sub woofer speakers and use the Panasonic centre and front speakers (i.e the built in ones). Then the sound (for DVD's) will come from the TV speakers for front & centre and through the AV receiver for rears and sub. The advantages for me is: -slightly cheaper, as I don't have to buy new front and centre speakers -less cables and no unsightly front speakers cluttering up my lounge -easy to use as my Panny auto switches to the DVD when I put a disc in and I can switch to DVD without fiddling around with the TV sound. Disadvantages??? -I'm not sure, but maybe a sound delay? -any comments?
