better to capture first on its native format, which is DV. saka mo na lang iconvert to mpeg2. masyadong mabubulunan ang pc mo, kapag sabay. kung mabilis naman ang pc mo ok lang, but mas mabuti pa rin idownload uncompressed, hindi kc cpu intensive when downloading on its native format.

anyway kahit idownload mo sya to mpeg2 kaagad you still need to have the same amount of hard disk space as downloading in dv format, kapag sinasave na lang ang file saka sya lumiliit sa size na mpeg2.

and as much as possible, exit all background program that is running like antivirus, u need all the memory and cpu usage you can get.
