That's interesting, as MPEG-4 (.mp4) videos are the preferred format.
That's the format youtube uses for Apple devices (Normally youtube uses flash, but it's not supported by Apple)
Other formats supported are:
If you've tried these, might have something to do with the site you're getting them from. As far as I know, the iPhone also formats as .mp4. Might be a problem with the iPad, so try restoring it (sync first) from iTunes.
Not sure the context of you trying these types, but perhaps this will help.
I found that my Safari browser (iPad or Windows Safari) also would not respond to MP4 file types I had links to on the web page I was authoring. Couldn't figure it out for a while.
Then, I realized that I had the wrong "type" attribute on the web page. Once I changed the tag to something like what is below, it worked just fine. In other words, it wasn't the browser, it was the page that was wrong.
<source src="videos/Test.mp4" type="video/mp4">
I did read something on another problem report discussing "agents" for handling file types. If my tip doesn't shed any light, perhaps look at the Safari Preferences, turn on "Show Develop menu in menu bar", then look at the Develop menu's User Agents options. Maybe one of them has the setting you need. This may not work, so I'm not prepared to add anything more to the suggestion.
I pressumed you were recorded 1080p using iPhone 4S, right?
The iPad [original iPad, iPad2, and the new iPad 2012] can play 1080p x.264 AVC or regular h.264 Video Stream with AAC audio 2ch / 6ch multi Audio Stream, multi subtitle stream, and chapter stream using MP4 Container.
However the original iPad and the iPad2 is forbidden for inputting the 1080p MP4 using iTunes
To play 1080p mp4 video thru iPad, there are 2 option:

Sorry for any grammar mistakes.
Greetings from Indonesia
For iPad you can play video other than mp4 by:
1. Using third party player: such as OplayerHD Lite that maximum 720p such as Matroska container, FLV container, AVI container.
2. Re-muxing the stream into mp4, it is possible if all stream such as x.264 / AVC / h.264 Video with AAC audio stream. Muxing only re-saving into other container, it takes 1 seconds to 15 minutes maximum for 1080p 2 hours movie.
3. Re-encode the whole movie to mp4, this take 1 hour to 1 night, if the stream cannot be player by iPad spec.
For option 1: Clear enough.

For option 2 : [Mac only MKV input- Subler], you can have the 720p /1080p subtitled m4v for 1-10 minutes

For option 3: Re-encode with Handbrake take long hours
Clear enough. With Handbrake you must re-encode the whole movie, but you can mux the soft subtitle also.
Maybe you need a video converter to convert videos' format. I recommend a video converter named Aneesoft iPhone Video Converter which can convert many videos to iPhone. The stable and speed of conversion are nice!
I think you can have it a try.
