I believe those parts are incredibly sensitive to bypassing. Read all the IR app notes and follow them to the letter.
I may be barking up the wrong tree, but at least I'm barking!

The driver must have it's own supply voltage 12-15 V. Worth noticing is that if you want it really good those drivers aren't good enough for class D. Compare how Bruno has done.

Still, if you want to learn more check also the HIP4080, 81 and 82 from Intersil.
