Video Capture Software

I got this video capture program for my sony DV camcorder but it alters the quality and changes the size when i get any footage off the cam...

Does anyone have a Video Capture program that lets u choose the frames u want to record and also not F**K the quality

My computer is a Vaio and I can tell I have some stuff install on it.The bundle came with this software if you want try it, for me is working very well not as fast as I want but very good quality.Here is link: http://www.sonystyle.com/is-bin/INTERSHOP.enfinity/eCS/Store/en/-/USD/LC_BrowseCatalog-Start?CategoryName=lc_cpu_vaio_software_clicktodvd&Dept=lc_cpu
