Powerpoint on the iPad using Keynote - Not Getting it

Question

This issue may cement my iPad's role as expensive paperweight.
I have a number of PowerPoint presentations, many of which contain video.  These presentations are for teaching physicians in radiology and are essential. 
The first part of my problem is opening these presentations on my iPad.  On the advice of other iPad users in my department, I've installed Keynote and I've copied a couple of presentations onto my iPad using iTunes.  When I open these presentations in Keynote, however, I get a message that movies are not supported and were removed.  The moves are embedded AVI's in the original PowerPoint presentations. 
To test if there was a codec/format issue, I went back to the original presentation on my PC and converted the videos to mp4.  I embedded them into a new presentation with only one slide and synced that to my ipad.  Same result.  Movies not supported and were removed.
So, my first question is this: Can Keynote for iPad play video in a presentation under ANY circumstance?
Next, if it can play video, is there some sort of trick or conversion step I need to go through to get my PPT presentations to play in Keynote on my iPad?  (If there is, I'm wondering what the point will be.  I have a lot of presentations for teaching, some of them with over 100 slides.  Yes, 100 slides.  And a lot of video clips.  They're quite large and I have no desire to essentially rebuild them or try crunching them through a lengthy conversion process.)
Is there something else beside Keynote that I should be using?  DocsToGo maybe?
I don't have a MAC and don't want one.  The iPad is the only Apple product I own and, so far, I can't find a use for it.  This is pretty much the last chance for it to be useful to me at all.  I do think it's a lovely looking device, but I'm not what anyone would call a media consumer and that seems to be what the iPad was designed for.
Any help would be greatly appreciated!
Thanks.

Information obtained from a product review on Amazon;
There are a few details you need to know to import media files this way.
  1). Create a folder on any SD card and name that folder "DCIM".
  2). Place media files into the DCIM folder.
  3). Important: The media file names have to be exactly 8 characters long (no more, no less), or the iPad will not see them.
Examples: 8letters.mp3, 8numbers.jpg, 8Numbers.mp4, TheBirds.mp4, Img_9001.bmp.
Those are really the main details, but here are a few more:
When you insert the Card Reader (one of two devices in the kit) into the iPad, with an SD card in it, in a moment the iPad screen will show thumbnails of all the media files on the card.
You can import some or all into the iPad. You cannot play media files from the card, you must first import them. To select some media files, just touch them to highlight them and choose "Import". Or, you can select "Import All".
The iPad will ask if you want to Keep or Delete (on the card). Be careful to select Keep (in most cases).
Valid video files need to be in the ".MP4" format, version H.264. Or convert them to that format using almost any conversion program (Freemake.com - has all current iPad video formats).
NOTE: the media files are imported into the "Photo" section of your iPad. Even the MP3's and Videos. So, to watch a movie, for example, select the Photo icon, not the Video icon on your screen (it won't be in the Video section).
AND, you can delete any media files after playing them. That way, you can, for example, load a movie or two into the iPad, watch, then delete to make room for others.
When I first tried to import the media files, I knew about the DCIM folder (it's the same as your camera would create), but the 8 character requirement I hadn't known. Only one media file showed up.
Remember, there is nothing magical about how your camera puts files on an SD card. The Camera Connection Kit Card Reader doesn't know the difference (there isn't one) and does not care, so long as it meets the requirements listed above.
