Hey, all. Newbie here. I'm currently flying a few of my band's gigs (VHS) onto the HD with a Canopus ADVC-100 and saving the files in Vegas 4 as .AVI files. I'm burning them on DVD-R with a Sony DRU-500A as DVD disks. The problem is that I can only fit a little over an hour onto a disk burning with Sonic MyDVD. Is there a reason for this? I thought DVD-R disks could hold a little over two hours of uncompressed video. Any thoughts? Am I doing something wrong? TIA for any and all help.
