I too vote for Ashampoo Burning Studio. You can also try
Burnaware .These two have freeware and pro versions.Free should do the work mostly.
CDBurnerXP (FREE)is also a great one which has all features of a pro version for free.though the interface is old it is quite powerful.
Freestudio (FREE)is also goo with a ton of features.
You can grab this giveaway also(VALID till 24th JAN):
