Okay, I just got to test the NAD T524 with both "home-made" DVD-As (burned with WaveLab 5) and commercial ones. It always produces gaps...
Interestingly, the cheaper Yamaha S657 did not have this problem. Instead of the gaps you get clicks that sound like the good old sector boundary errors that we've all grown to love...  ::)
The Yamaha S1500 (which is more expensive than the NAD) worked flawlessly.

Please file a ticket at the NAD website (http://www.nadelectronics.com/help/) and also at the local distributor for your country.
I find this bug quite unacceptable.

I got a reply:

Q: Do commercially made (pressed) DVD-A's with live, continuous audio work OK?

A: Yes, the T524 should play these discs perfectly..with no skipping issues

Q: Do DVD-A's burned by other setups work OK? (is my software bust?)

A: We have not tested any burned DVD-A due to the fact that non commercial DVD-A's are not usually available.


So now I really need a pressed DVD-A with continuous audio to test this out.
Where in the EU or rather Netherlands could I get a pressed DVD-A with live, continuous music with track marks in between?
I mean: local record stores (Free Record Shop, Music Store, etc) don't carry other stuff that loads of DVD's (video) and a few CD's.
What online retailer in the EU has a selection of DVD-A's?
What funk/rock/jazz title would fit my requirements?

Beck? (see how little info a sales page has...)
It does have live audio? (could not verify from the site)

Thanks for the tip!

oh, it's not live, but you would be able to hear if there's a gap i think

or just get Yoshimi Battles the Pink Robots.  it's got continuous tracks

Another very promising reply:

We will not be addressing this issue with a firmware upgrade.

All T524's will play the same with burned DVD-A's. This is not a format that we expect the T524 to support. It should support store bought DVD-A's.


So the refuse to even research and do not even provide an alternative.
They DO support CD-R but DVD-R (-A...) is of course imposisble.

Does anyone know if the other available NAD DVD-A players also suffer from this problem?

i doubt it's a dvd-r thing.  if a burned dvd-a has gaps, i'm betting a commercial one will, too

I was told that gaps (as on track-at-once CD's) don't exist on DVD-A. I guess so.
Can anyone confirm?
The drive in the T524 reads the DVD+R's I use without problem. DVD+R support  is even in the product spec.
So they give the same support (probably less) as the manufacturer of a cheap $50 DVD from far away.
The local distributor does not even respond to my emails.
Also they don't have other DVD player models.

So what is a nice alternative for the T524?
It should be available in Europe, same price range as the T524, darkish case colour, support DVD-A, support progressive scan.

Exactely. I tried "Hotel California" on the 524. You don't hear the gaps (because there's no continous music), but can see how the counter kinda jumps back a bit as a new track begins. As I said above, this is not just an NAD problem. The cheaper Yamaha player did something similar.

a lot of players do it...it is a buffer issue.  The Samsung HD-841 did exactly what you described. The Pioneer Elite DV-45A I know doesnt produce gaps.

Well, I will  check out the T524 with some pressed DVD-A's and if these produce similar issues I will continue my offensive...

New reply:

Our engineers are going to investigate this further. However, we do need to ask for your patience as it will take awhile for them to look into this. We will inform you of our findings as soon as possible.

Hmmm. I first have to compare them to a manufacturer of a $50 DVD-player before they seriously look into the matter?
I wrote:

Your product info for the T524 specifies:

Plays DVD-Video, DVD-R, DVD+-RW, VCD 2.0, JPEG, DivX
Plays DVD-Audio*, CD, CD-R, CD-RW, MP-3, WMA

a) So the drive will read burned DVD discs. (+ and - even!)
b) Also the T524 is said to play the format of DVD-A.
c) So the drive can read the DVD-A format from my burned DVD+R
d) Therefor it should be able to play the disc I made
e) It even does play the disc with so far only one fault: the skips at the track changes!

Update, just sent NAD:

Hello,

Just tried the pressed DVD-A of Curtis Mayfield Live at Ronnie Scott's and it suffers from the same phenomenon: it skips when a new track starts.
So your product officially has a flaw.
Please confirm you will fix this bug in the buffering of the audio stream.

Thanks,
Udo

BTW: Who knows the requirements for a player to be able to carry the DVD-audio logo?
