Help with XCode project playing video

I have an OpenGL XCode video game project. It plays an .OGV video as the background however it seems to only be able to play a video that is 128 x 256. I would like it to play a much larger video (something around 512, 1024). That's all I need. I've attached the class for your review. Thank you for considering my project. Have a great one. ## Deliverables Here is the class (attached).
