I only have two dvd-a discs right now (others on order) and I had to send my Panasonic Rp-91 dvd-a player back to Panasonic for a replacement. I tried playing the DD 5.1 tracks in my Toshiba 5109. One disc, Chanticleer, played perfectly but Fleetwood Mac's Rumours will not play the DD 5.1 track at all. The "Loading" just keeps flashing. Has anyone had incompatibility with a dvd-a disc and a regular dvd player? With Rumours and a Toshiba dvd player in particular?
