@candyquilt-- I use a free streaming video recorder too but the quality is good (same as the original) and so is audio. I suggest trying a different software. Also read reviews and descriptions to make sure that the software is compatible with your operating system and the types of videos you want to record. So if you specifically want videos from one site, make sure it works for that site.
I'm guessing that you just used a bad software or it was somehow not compatible, or had low capacity.
