This software has saved me hundreds of hours. Probably like most people on this forum I watch loads of online video. I use this software to speed up my videos by up to 3X as fast, without losing quality of sound.
I can get through a 1 hour video in 20 minutes. It's not free but costs roughly $30 to view online flash videos and about $90 for the offline version. I don't want to put a link in here but if you go to enounce.com check it out.
It's especially good for those annoying sales videos without fast forward on them!
Anyone else have a must have tool or software they want to share?
