HAHAHAH. Awsome! Also have a liteon 52x burner, also burn 48x media at 52x, also never had a problem. The only thing is that it's pretty damn loud at full speed. My DVD-ROM drive is supposed to read at 52x (CDs), and it's nowhere near as loud.
I often copy DVDs to DivX and burn them onto CDs. I usually split a movie to two discs. So later, when I'm watching them, I put one in my CDRW and one in my DVD-ROM. During the first half of the movie, the CDRW drive is spinning and is audible even with the speakers pretty loud and me sitting on my couth across the room. You get used to it, but during the second half, when the DVD-ROM is reading the disc, it's so quiet. Kind of like when a washing machine or fridge shuts off; you don't realise how loud it is until it's gone.
