I am using iDVD 7.0.4 and OS X 10.5.8 on a late 2008 MBP I am burning about 220 minutes of footage on DL dvds and find it takes nearly 7 hours to encode and burn. The burning portion only takes 30-40 minutes. I am trying to find out: 1) if anyone else has packed a DL dvd full and how long it takes them to burn it. 2) if there is a better/faster program available. Another thing i am curious about is if the warning that pops up when i choose to "Save as Disc Image..." is legit. It says: "Double-layer disc image compatibility: DVDs created from double-layer disc images may not play well in some DVD players. >If you use a disc burning utility to burn a double-layer disc image, the DVD may not play well in some DVD players. For best results, use iDVD to burn double-layer projects directly to a DVD." I wasn't sure if this was to discourage using iDVD for nice menus and then using some hack-job burning software or what. And how do you burn the DVD from the file that is saved? Last bit: I just burned 2 copies of the same Double-Layer DVD and both work in both my MBPs but my xbox360 will not recognize them. The discs are Memorex DVD+R DL. Also, any insight as to if these dvds will work in a regular dvd player (dont have one) or if i just have a crap game console that cant play DL?
