If something was shot on NTSC or PAL video, I'm more inclined to buy it on DVD. An HD upconversion done with pro equipment might get something out of it but it won't be that much improvement from the original video source (retain the full verticaI color resolution that DVD's mpeg-2 halves, deinterlace 60i video properly, etc) but at the same time I think that by the time lots of shot on videotape content hits BD release, we'll probably have equivalent software tools to watch them in as good quality. And that's not even counting that the HD conversion might not be done optimally. Of course if a particular videotaped DVD is a favorite and the BD comes out done perfectly later, there's always double dipping to the rescue!
