While streaming it keeps buffering.

How do you clear the cache?

Have you tried clearing you cache first?

it's basically the same as streaming a movie, you just can't "buffer" if you can start netflix let it load then play without "buffering" at 720p, then you would be able to stream with gaikai.

I would vote if the browser would let me (keeps telling me 'We couldn't submit your vote at this time.'). But honestly I doubt this will happen, my guess is the agreements they have with content providers like Beachbody specifies they only have a streaming
license and specifically prohibits saving to disk.

Although if that is true it doesn't mean they can't improve. The streaming has been pretty solid for me lately, but on those few off days where I do have issues it seems like it could have been prevented. Xbox Fitness seems to only buffer a tiny amount of
the video. When your connection acts up only a little bit it can result in switching between HD and SD multiple times, or it just runs out of buffer. Simply buffering more seems like a relatively easy solution to most of the streaming issues. Take Youtube
as an example, once you start to play a Youtube video it tries to buffer as much of the video as possible. Even if you pause a Youtube video it continues to buffer. And not unimportant, the use can see how much of the video is already buffered. Just having
a bigger buffer in general should lead to less hiccups, but when a connection really is questionable a user could simple pause the video at the beginning and build up enough buffer so the video will play smoothly.

You should test your connection. You could be experiencing low quality because the system is unable to stream anymore. Netflix has a similar system where the quality will lower if it can't keep up to avoid buffering.
