The reason I was asking about -R dual layer recording media is the fact I purchased a Pioneer 550 HS 'stand alone' unit.
I thought the 550 HS only recorded in -R DL format. If it also records in +R DL format, that may answer my original question...
I am looking for a recorder that also has hard drive capability and something I can situate with my TV/home theater.
If there is a different/better DVD dual layer/double layer stand alone unit I am all ears... I would welcome any helpful suggestions.
I DO NOT want to use a PC based solution - too many reasons to go into here - suffice to say I don't want to go that direction.
Thanks in advance for any help!
