Thanks for the replies....I'm not all that confident.
I've Encore authored footage I shot of my wife's business (no...not pRon). Usually with Encore, I transcode to ISO and burn to RW for checking. If the disk checks out okay, I rip the files back to the harddrive and burn to '+/-R' format. One thing about Encore ISO's, is that they don't include the always present, and usually empty, AUDIO_TS folder for increased compatibility.
I won't have this luxury with DL media. I may be able to go directly to IFO, VOB files from Encore.
@JSL - What version of RecordNow does the job with DL media? I do run version 4.5 with my Liteon/2500 burners. It's mighty old now, and sure it doesnt' support DL.
@fritzi93 - Yeah, I've read some stuff from Edmund Blackadder on the subject at Videohelp.com. I'm just throwing the subject out on this forum to broaden my research.
The layer break seems to be the tricky part. I know support for dual layer is in Encore.....I guess I'll be doing some of my own testing....ouch my pocketbook!
