I have the Sony HVR V1P and have been recording in HDV mode and am thinking of switching to DV mode. Somewhere in the editing process I have been losing the HD which is evident when I post to Youtube although I cannot complain about the vision (good quality). Can anyone tell me the pro's and con's of HDV and DV? I use Pinnacle Studio 14 Ultimate Collection, I have a computer with 2Gb ram and 3Ghz CPU which I know is not optimal but until recently has not been a problem. Just lately it's starting to do strange things and takes ages to render. I have deleted auxillary files which I was told should be done regularly to clear space. I don't have many programs running and have saved past projects to an external hard drive. Any help would be appreciated.
