There is a solution if you're technical minded. For users who do not wear buddy holly glasses, this is gonna be a little daunting and probably isn't worth it.
In a nutshell - some video streams are shown via flash, which apple has officially written off. So iphones and ipads can't view those streams. But it's possible to install flash via an unlicensed 3rd party program. To do that though, your phone must be unlocked (jailbroken). Non-jailbroken phones will only use licensed apps that apple permits.
Jailbreaking the phone is not hard, but it carries some risk. The process varies depending on how new your phone is. From what I understand, apple has taken steps to prevent it with newer versions of their phone operating system. But you can roll your phone back to an older operating system and work around this.
Here's a link covering the risks of jailbreaking your iphone:

The worst of them is that your iphone is ruined and unusable permanently, and you'll have to buy a replacement.
If you decide you want to give it go, here's instructions for downloading and installing the 3rd party safari flash plugin. Instructions for jailbreaking your phone and installing it are also here, but they appear dated. You may want to google for "jailbreak iphone" followed by your phone's OS version number. Try to find the most recent information possible.

Lot of risk just to watch pool on a screen where you probably be able to see the difference between the 1 and the 9. But I thought I'd throw it out there.
2 disclaimers I should throw in:
- no guarantee even after all this that the video will play. I doubt anyone is going to rush to do all this in the next 3 hours and then buy the TAR stream just to watch on their iphone. But just to be safe I'll say it. Flash is constantly updating and there various ways to implement flash video. I wouldn't even hazard a guess as to whether the tar stream (or a typical ustream) will play with the method above.
- this IS legal for those sweating it. It's your property and you can screw with it however you want, including bashing it with a hammer. But it does void the warranty, and technically your monthly service could be terminated too. I don't think that's likely but everyone should know the risks. I know people who have done it successfully and are happy with the results.
