I guess I don't like to told what I can't do, I using a DVD Xpress Video Capture Card (box) with S-Video from Voom Box recording at 9 MB/S quality
with 5.1 surround audio to a 1/2 terabyte SATA / 7200 rpm Western Digital drive system to a Media Center HP 1090 computer with XP Pro Media Center 2004 Edition viewed on a ATI X-600 Pci-Xpress Video card  with a Sony GDM 5411 Professional Flat black Screen Monitor  with a resolution of 2048 x 1536 @ 75 hz  
It's as close to HD recording  and viewing as I can get without it being HD 
By the way for those of you who want a Monitor for your PC and near or beyond HD
