I have had alot of success using both of these. Recently I boght Nickelback Sturgis 2006. When I copied it into High Res Ipod format, the first few minutes where the band is back stage played fine but as soon as the comcert started the video is fine but there is no audio. I also tried to import Tesla Comin at ya live 2008, and DVD43 didnt even recognize a disk in the drive. I put another disk in and DVD43 worked fine. I updated DVD43 and retried eveything. Nothing changed. Is there some new protection these disks have?
