How do you capture frames at DVinfo.net

I am consantly let down by the poor quality of a frame grab made by Sony DVgate Still. I am using a PD150, but I don' t think that really matters, and am capturing with DVgate Still on my notebook. Really what I want is a good quality jpeg file.I know that using progessive scan increases the quality, but still it doesn't look too good. Is there anything else I can do to improve the quality, or is there third party software / hardware which will help? I haven't tried it yet, but hopefully some one has, what if you were to play the video and do a screen capture. Would that improve the quality?

I use Premiere's export-frame function and when you mentioned screen capture I was about to rail against the low res, usually 72 ppi. So I opened a couple of exports in Photoshop and they are also 72 ppi. At 30 of them per second it's no wonder that the DV stream is 3.6 MBps. But even at that they are only about 120 kb per frame and that's not much information for a still. Even 3-CCD cameras using the still function don't take high resolution stills, although some new entries are beginning to go there. Everything I do with still images is either web or ink jet directed (unless it's back to video) so the res is ok with me, but I am upgrading my digital still camera next month, because I want better images too, and they won't come from my VX2000.
