Keyframing Animated Textures

Hello, i was very reluctant to post again since my last topic was techinically ignored leaving me no option but find out by myself how to do things… sigh… spending 2 months figuring out things that weren’t that hard…
well here i go again, i have two problems at the moment that i can’t solve yet; if i want to use a image sequence as texture or video as well, i don’t have the animated result in Game Render or Blender Render, just a random frame of the whole animation, at the time of testing i have this already setup:

-Viewports with GLSL, Textured Display
-An UV Unwrapped object, be it a cube or a simple plane (in GE, animated texture is enabled)
-A basic material, merely at it default state
-A Texture with Sequence/Video Type, in this case a sequence of 12 images
-Image options: Premultiply, Mapping: UV Flat, Image Sampling: not alpha and box filter, not mipmap and no interpolation, influence in color only
-Settings for the sequence are:
(1)Frames12 (assuming that each frame is an image of the sequence and the number between parenthesis is the current frame )
Start:1 - Because i want the sequence start at frame 1
Offset: 0 - Because i want the first image being the first frame of the animation
Fields: 2 - As far as i understand 2 is the average number for 24 fps, while 4 is 12 fps, more or less.
-Same settings in GE UV Unwrap mode
-Auto Refresh and Cyclic are enabled.

After all this, the animation is somehow working by pressing play button or with arrow keys, but trying to render the animation or pressing P for Game Engine only shows a static version of the supposedly animated texture. what i think i need for a properly animation with textures is keyframing the image sequence, but i can’t find how to do this, i see options like animate the offset or the position, but nothing related to the sequences.

Long story short:
1.- Can’t visualize the texture animation in Blender/Game Render
2.- Can’t find how keyframing the animated texture (sequence and/or video), i find this useful for ‘actions’ in further projects

thanks if anyone take the time for answer

hello H13N.H3N
I tried again, and with the latest version of Blender 2.55, it works.
The offset is the number of the image you want to display.
You must settle the points of curve on a constant interpolation.
There is the blender file as zip, I cant pack the textures in the .blend :
