Sony Blue Ray: S5000es vs S2000es

I have the S5000es; and I find it to work very well; I am using 5.1 analog out; and having the BD process the new codecs; running it into analog input card on Meridian 861. I have played both standard dvd and blue ray; it's load and start times are very good; and I've had no problems with difficult to play...
Unfortunately; most of the bd discs I've used are only 5.1 dolby digital; few have new codes on them; not sure I've heard big benefit of improved sound; but picture is exquisite. Lot's of options in this price point; the sony is a bit steaply priced.

Thanks for the responses so far. Just talked to Sony and they are sending me a firmware update disc to take the player from Version 3.0 to the current 4.3. Hopefully this will fix my frustrations.

Mribob- Do you have a feel for what your load and start times are for Blue-ray discs with your 5000?

Thanks

Does the update disc fix the 2000 so it will play dts-hd?

I just played a disc in DTS-HD through the 2000 - not sure if the sound was processed by the 2000 or my processor (Integra 9.8). Regardless, the sound was extraordinary.

Dear Fplanner: I timed my 5000es when I loaded a disc; from opening tray to having disc loaded and images on TV was less than 20 seconds...I do have it set up in 'active mode' not standby which reduces the load time; but uses a bit more electricity; not too Green for me...
Hope that answers your question.
