With the recent price drops on Pioneer's DVR-A03 and the introduction of HP's DVD100i, it looks like recordable DVD's are here. The problem is trying to figure out which one is most compatable with other home players. The HP claims DVD+RW, where as Pioneer claims DVD-R, DVD-RW. Both will record DVD's and the media runs from about $10-15. Does anyone know which is best or has tried any of these units?
