Limited number of video files visible in "my videos" scope

The "my videos" scope in Touch seems to have a limited number of videos it will show.

(Beyond that number, the only way I've found to access them is through the Gallery app, as the file manager doesn't execute files.)

The number it's limited to seems to be 100. That looks like a deliberately-set limit to me, and surely it's too low for even the basic bq device with its 40GB of memory.
