If you're looking for hosting for PHpMotion V2 and V3 you will want to go with HostUpon.com

PHPMotion hosting at HostUpon is fast and they all all of the ffmpeg modules you will need to stream, upload and convert videos.  You will need to choose their Business Hosting plan as it comes with ffmpeg.

The Business plan also comes with a dedicated Ip address and is a little faster it seems than the regular shared hosting.  We installed and tested phpmotion with no issues and our account was setup within a few minutes.

The support staff is VERY friendly and helpful and our overall experience was positive!

PhpMotion is a great script and HostUpon.com is the perfect host after all of our reviews.
