blip.tv videos corrupted after using edit function in wp

I have videos cross posted from blip.tv

https://www.overlander.tv/wordpress

When I use the edit function in wp with any of these video posts, the videos no longer play embedded in my site but instead one is asked to download the .flv

blip.tv have just informed me why the videos dont play embedded in my site and instead just try and download flv:

So I think the problem here is that WordPress thinks it’s smarter than
you. This causes problems in two ways.

First of all, when you use their rich text editor to edit (or copy &
paste) anything that includes JavaScript or Flash, it tears the whole
thing apart because it’s not sure if you’re writing code that’s supposed
to be interperted or writing stuff that’s supposed to appear verbatim.

The second problem is that WordPress, after already kind of uncertainly
treating the copy & paste code (or the cross-posted code when you edit
it) will then try to “balance” and otherwise “fix” your HTML. This,
again, can cause all sorts of problems with “advanced” code. Believe me
when I say that we never send a “<u />” through to you. That’s
something that WordPress did because it thought it should. I’m sure
that at some point something was underlined, and it’s likely that WP’s
parser couldn’t easily find the end of the thing that was underlined.
Something like that.

Can someone please tell me if there is away to avoid corrupting my video posts when I edit in wp?
