ADTS maximum frame size?

Ok, I have a test ADTS .AAC file that plays fine through VLC, but when I try to use a third-party player (sorry, I can't specify which one) I get a nice error informing me that it's found a frame > 2000 bytes in length, and it barfs and dies.

Now, there are 13 bits set aside for framesize, so I'm thinking that this error is a bug in this product.  HOWEVER.. I'm wondering if, perhaps, it's actually a bug in the test .AAC file!

Is there some magic number less than the 8192 that 13 bits will allow that's a limit for ADTS frames?

All info appreciated!

Simply said 6144 bits or 768 bytes per channel per frame (there are some more rules but this is what is comes down to).

Argh! That would mean that the authoring app that was used created a file with bad frames in it...

I can see I need to dig a little deeper into all this.
