These capture card devices are generally "plug-and-play", if software comes with them, it's usually a bare-bones(cut-down) version of a popular editing software thrown in for the desired purpose, but when a user starts to "explore the possibilities of the software, he/she is disappointed to learn that in this bare-bones version, many of the "features" are not available. The capture card itself, is effectively a stand-alone device that will work with any editing software. It's far better to chase down a full version of the editing software than settle for the bare-bones version that came with the device. As for quality of performance, the old adage, "suck it and see" applies. If the capture device delivers a reasonable quality feed to your computer, well and good. If not.... well..... always try for another later. The first one I had, gave good video feed but the audio quality was attrocious, I bypassed the audio connections and fed the audio in via the line-in of my computer, had problems in that department but better that than the horrid audio delivered by that first card. The next card was a Pinnacle "Dazzle", it did the job, and gave good audio but then I struck a problem where I was getting false triggers of the "copy-protected" warning. I learned later that the false trigger was due to the condition of the tape. The capture card I'm using now does the job just fine for me(K-World brand).
