Comment 42 for bug 266951

I do confirm the same problem on my HP laptop (6530b). The ubuntu 8.10 installation from a CD wen well but I cannot read any video DVD. The DVDs are fine (I checked them on a DVD reader) and the laptop is fine as well (I can read the DVD OK when booting on Windows)

lshw output attached
