Sound Problem with DVD

[simrat]

Hey guys,
I always watch movies on my DVD-Player.Yesterday i formated my PC and now i have a problem. When i Burn a dvd and want to watch it on my dvd-player i have some Sound Problems. The Video works fine,but the sound lags(its not out of syn it just stops). I had this problem b4,but now i forgot how i fixed it
Everything worked fine b4 i formated my PC. And when i open my DVD drive my pc loads a lot and when i burn the dvd it loads a lot,too.
I tried to burn it with nero premium,tmpeg dvd author 1.6 and CopytoDVD,but everything failed. I think my CD drive is Master and my DVD Drive is Slave.I dont think that this is the problem coz it worked fine b4 i formated my PC.
System:
Windows XP Pro SP2
1000mHz
DVD Drive: NEC_DVDRW ND-3520A
i didn´t install any drivers for it but it worked fine without drivers before

Ensure you have the latest MB drivers (IDE drivers) and that DMA is enabled.
