taking lot of time to write dvd

[gau_pppu]

my sony dvd writer (DRU-810A) is taking about 1 hr to write a full dvd ie around 4.2 gb, i genarally write dvd at 12x, where as my drive is 16x. previously it took just 15to20 min max, the writing is absolutely ok, it can be easily read in any computer, but the fact is that it is taking lot of time to write, my drive is updated with the latest firmeare (810A_1.0f),
no problem in writing cd, plz help me out ..
