0.9.6 is way too old and dangerous!

Okay, I installed 2.0.5 today and it is not usable for playing DVDs on Win7-64. It will play them, but the quality is not acceptable.
1. The video playback is still not smooth. It was smooth in 0.9.6. You did something that degrades the playback starting with 1.x.
2. There is now an audio dropout every couple of seconds. I tried wav and directx.
It's not a system problem, it's in vlc.
