@Logos: bug with flash players should be already fixed now (I think there was a problem with x64 registry virtualization component). If build 661 didn't help, please write me which browser you're using + example web url.
okay I don't know what to say, I just checked again and it works now. It just didn't work at all with any site featuring flash videos, using the latest 661 build, and now it does
someone else in this thread was saying the same and I didn't believe him, but that's true, after a while, it starts to work
ps: when it didn't work, that was with Firefox and Chrome using flash, but Chrome using the built-in flash always worked.
