NBA on ESPN (ABC) CHI @ NY

WABC-DT NYC FiOS.

PQ is ok. WABC has an HD sub channel so it takes away from the video quality.

What I find odd is the audio mix.
The arena sound in the L & R front are as loud as the announcers in the center channel and there is almost no sound in the rears.
If you are listening to the DD 5.1 audio down mixed on a TV with stereo speakers the announcers are at times totally lost in the sound of the arena and impossible to understand.
Is this a normal audio mix for an NBA game on ESPN?

OKC @ LAL
Once again the arena sound is much louder then the announcers.
On a stereo down mix by the TV they are very hard to understand.

It may not be intentional but again today on the down mix from 5.1 to stereo the announcers are at about the same level as the crowd and can not be heard clearly.

When I switch to WNBC-DT for WSH @ NYR, granted there is no music during game play like the NBA, the announcers are a little easier to hear on the 5.1 to stereo down mix done by the TV.
