I just canceled my subscription to traffic geyser. After being a member for a couple months, I did see a lot of people say they are getting great results. I personally feel it is an excellent membership that will get you good results if you use it to it's fullest potential.
I myself only uploaded a few videos. The results I got were not what I had anticipated. I ended up seeing only a few entries in google and all were like page 3 or lower. My youtube video is now on page 1 but I believe that's based on other efforts. Like anything, it all depends upon competition.
Bottom line is traffic geyser will allow you to create lots of great back links from the video sites as well as submitting to podcast directories and rss directories all at the same time. If I were at a stage where I had more videos to submit on a regular basis, this might be worth keeping for me.
Although I can afford the $97 a month membership, it isn't worth paying every month when I'm not truly using all the service has to offer.
What I now plan to do is get video post robot in conjunction with RSS Submit along with the podcast plugin for RSS Submit. ( hXXp://www.dummysoftware.com/rsssubmit.html NOT Aff. link) I have not used either programs yet but from the looks of it I can achieve basically the same agenda as traffic geyser.
Traffic geyser is great because it is fairly simple to use once you submit your media a few times. It automates the whole submission process for you in a very quick period of time. They also have a lot of support material and an active forum. Results will vary with your niches but in the long run it's creating great back links for your sites.
If you're ready to pay $97 a month for it, and you will use it regularly, then it's probably worth it to you. If not, I think video post robot will probably be a great alternative. Once I get it I'll try to come back here and post my experience with it.
