The severe limitations are simply that you're not getting a worthwhile 
processor.  Hardware decoding is inherently inflexible.  You have 
whatever capability was burned into it during fabrication, and that's 
it.  Should you ever want to do anything the decoder is not capable of, 
you have to fall back on the CPU, but in the case of an Atom, it does 
not have sufficient power to handle whatever you want in software.
