my sony pcg-f610 550 amd chip, I installed a toshiba sd-c2202 dvd rom. it pays regular dvd ok not like my new hp laptop, but ok non the less, it plays a bit slow not that u would notice. I guess am picky about these things. I was wondering if anyone has ever installed a dvd rom in a laptop that didn't have one that came with it. the pcg-f630 has one so I figured f630, f610, what the heck. I also have power dvd 4 as my player, that's the thing that gives me a an error msg(unk error powerdvd will now close). anything from anyone thanks.
