From my past experience, i used to buy cd and dvd...
if u buy in small amount then no tax kena
if u buy in bulk then have to declare probably or may kena tax
usually if u buy lot of cd dvd better split the shipment
or else custom ll call u up to collect urself
but can select Pos malaysia as ur agent but need to pay them Rm49.5 charges!!

if u go get the cd urself nd to pay declare form EDI RM18
and then nd go here go there get chop KDN

However, everyone must bear in mind that only item that more than RM500
ll kena tax if not there should be no tax for cd dvd vcd
vcd, cd tax 20%+10%
dvd 30%+10%
but usually they tax is exempted as value below RM500
so pandai pandai when declare la:-D
