I have been trying to get dvd-rw to work on this player. Grundig say it should work, another poster here says he can do it burning disks on a mac, but I am having no luck. I can burn dvd-r that will work fine on the player so I don't think it is my authoring. I have tried 3 or 4 different burning programs. Anybody have any ideas? Could it be the media? I am using Pioneer disks and burning on a Pioneer DVR-A04

Thanks
Glenn
