Here's how to download the app so you can watch WrestleMania 29 on Sunday, but remember you have to have a gold membership to do this.
1. Go to the apps section of Xbox live
2. Choose browse apps
3. Go to video then choose see all
4. Go to 47 of 47 and there it is. Just select WWE pay-per-view and download it.
After looking it over, it's not free by any means. You need to go to www.wwe.com/ppv to sign up for an account so you can view WrestleMania 29 on Xbox live.
Sounds like they did this so those who don't get pay-per-view can buy it and stream it on their Xbox. The cost to stream WrestleMania 29 is still $59.99.
