Have filled my Sony 300 CD store and was considering Yamaha HDD till i saw the price! Now aiming at a DVD recorder with large HDD capacity - previous threads have helped. Would use part for AV and part for music - need to link PC to unit for digital music therefore. None have 'optical in', Pioneer and Tosh provide 'DV/firewire' and Panasonic units have SD cards as possible but imperfect solutions. Will the units upload 'burnt' CD's? Or have Apple got it right streaming music from PC, wirelessly, to Airport Express which then can connect easily to my amp - superb organisation of the music included. The combined AV / music HDD player seems a long way off!! Comments please.
