Google Video streams content via Flash, which is not supported by the iPhone. However, there is a simple workaround for playing Google Videos on your iPhone. Simply choose a video you'd like to watch (be sure it is a Google Video, and not a Youtube video, which is also integrated into the search now), and follow these simple steps:
1. Scroll over to the right side of the page.
2. Next to the "Download" button, activate the drop-down menu, and choose "Video iPod/Sony PSP."
3. Click "Download" and you will get some drop down text that says: "If the download does not start automatically, right-click this link and choose "Save As"."
4. Click on the link it provides, and your video will start to load.
5. If it does not begin playing automatically, click the Play button on the iPod.
Voila.
