10/27 Smackdown taping

I didn't really know where else to put this, so I'll go with it here.

I'm going to the Smackdown/ECW taping this Tuesday (10/27) and I'll be glad to post how everything is. I just have one major question... The advertised start time is 6:45 PM. Will I miss anything if I arrive on time? Or do they run dark matches prior to the start time?

I'd greatly appreciate it if anyone could answer, and mods... if this is the wrong place for such a question, feel free to let me know and I'll happily place it where it belongs.

Thanks!
