Online video infrastructure companies are in high demand these days, and they’re taking advantage of the opportunity to haul in cash. Dan Primack of Private Equity Hub has the scoop on two deals: Move Networks recently raised $34 million, and Acinion took in $16 million.

This brings Move’s total venture capitalization up over $45 million from firms like Steamboat Ventures and Hummer Winblad Venture Partners, while Acinion now has raised around $21 million from firms like Globespan Capital Partners, IDG Ventures Boston and Sigma Partners (new to this round).

We’ve been impressed with American Fork, Utah-based Move, which provides video streaming platforms for customers such as ABC, the CW, and FOX.

However, a Move spokesperson claimed in an email to NewTeeVee that Move would soon be “the undisputed big money raiser in 2007 in online video space.” I’m not sure that’s a title anyone should be boasting about, but it’s clearly untrue if Primack is right about the number: Dailymotion also raised $34 million, Joost has $45 million, Hulu has $100 million.

Acton, Mass.-based Acinion is said to be making servers specialized for high-definition video, though we haven’t heard of it launching a product or signing any customers yet.
