Hi all. I'm looking for some info regards the DVR-7000. 1: Can it record NTSC input through either component/s-vhs inputs? 2: VBR recording on a -rw disc - if I only wanted a half hour program/video recorded, would this fill up an entire disc, (4.5 Gb), or would it be less than 4.5 Gb. I would like to be able to use VBR mode for desktop video/DVD authoring. 3: Anybody tried extracting a VBR file from a -RW disc via a PC's DVD-ROM drive? Were the results good/bad? TIA. TBXP.
