Redkawa posted this news yesterday:

Red Kawa is proud to announce the launch of Wii Media Center X and PS3 Media Center X.

While the Wii wasn't designed to be a media hub, there's no reason it can't be thanks to the functionality of the Wii Oprea Browser that is now available. Wii Media Center X lets you stream your JPG, GIF and PNG images, MP3 audio and FLV video from your computer to your Wii. You can create FLV videos yourself by converting your original videos using our newly released version of Wii Video 9 (1.93). The video codec used the FLV format is a lot more efficient that MJPEG and you are no longer bound to using SD cards to store videos.

PS3 Media Center X is the successor to the Red Kawa File Server. It includes all the file serving capabilities of Red Kawa File Server as well as other media streaming capabilities. The Red Kawa File Server has now reached end of life status and will no longer be linked to from our webpage.

PS3 and Wii Media Center X is a web based media center which streams media to the Wii or PS3 Web Browser. It CANNOT stream media directly to the Photo Channel (on the Wii) or your Photo, Music and Video XMB menus (on the PS3).

They also followed up with this newspost:

Now that the Wii Opera Browser has finally been released, we were finally able to test Wii Media Center X on the Wii and like a lot of you have mentioned, we've also noticed that there are major issues.

Since the Wii browser only supports Flash 7 and does not support LiveConnect, you will most likely encounter problems using the slideshow or my music features. Also there are reports of choppy video in the My Video's section.

We wanted to let you know that we are aware of these issues and are working on fixing them. Our plan of attack is to first get the Video section working well and then move onto the other sections.
