you can go on the ultimate fighter and watch all the episodes for free
can you watch the episodes from the website on an ipod touch?
You can try using a web browser, but the only way it will work for sure is if you buy and download the episodes from iTunes then copy them to your iPod.
If the iPad still doesn't support flash, you might want to check and see if the website is flash based. Other than that, it should work with the browser.
All of the episodes should be somewhere on Spike's website as well.
