i bought a new liteon 48125s burner a couple of weeks ago(very nice btw
) and cdrwin 4 did not recognise it but i installed cdrwin 3.9b and it found the burner straight away so try using cdrwin 3.9b as it's the latest release!
cdrwin 4.0 was only a beta check out the cdrwin homepage at
www.goldenhawk.com
and as zedy said do NOT install cdrwin 5 on your system or u will have nothing but trouble,it's not a official product and is very badly made!!
