Cannot support high resolution 320 x 240, what does that mean ?

Question

When trying to e-mail myself a video recording from my cell phone it says, " Cannot support high resolution 320 x 240 "

What does that mean ?

My other resolution option is 176 x 144, I recorded some funny videos of my drunk friend, but I recorded under 320 x 240.

I have a feeling that If I record a video now under 176 x 144 it will let me send it, but now I have nothing to record.

What's the difference between 320 x 240 ... and ... 176 x 144 ?

Answer 1

176x144 is much smaller than 320x240.  Why not just transfer the video directly to your PC?
