Driver's side axle won't come off

Hi all, I could use some help. I'm following the the steps on the 1A Auto video I'll link below, but I can't for the life of me get the axle to pop loose - everything is off of it but no matter how hard I lean into a 18" pry bar the thing just doesn't go. I've tried whacking it with a hammer, rotating the axle to another position, etc but so far no luck.

What's the trick to removing this? I have to R&R the thing because the #@#^@#%!! spindle got stripped when I went to do a wheel hub, classic case of a job snowballing. Thanks!

Here's the vid:

 

Finally got the thing off. While the approach TMR-JWAP offered would probably have worked well I didn't want to deal with the mess (I drained the transaxle anyhow since it was due for a fluid change). What worked for me was to get a piece of wood that just fit in the gap between the top of the fat part of the axle and the overhanging part of the transaxle. This meant the lever I was applying to the bottom of the axle didn't turn the spindle sideways and further wedge it in place. Still took a lot of force, but the thing did pop loose that way. Happy dances ensued.
