Although most of my capturing will likely be of VHS sources that will be captured through S-Video, every now and then I'll be wanting to capture some cable, which comes through coaxial. Now, the PDI doesn't have coaxial input. I could buy an adaptor that does component/whatever else the PDI supports, but I've been told that would sort of defeat the purpose of buying such an expensive (for a consumer level) card. Is that true? If so, do I have no choice but to buy a second card for coaxial sources or would using an adaptor still be a better choice? Finally, if using an adaptor is the correct alternative, which ones would you recommend me?
