Hi,
my Nortek NDVX 100 player (based on ESS Vibrato1 chipset) doesn't
really understand AR settings, whatever codec and program I use:
it shows black video and no audio.

Did anyone get to play such videos with a different player?

Thanks.

What do you mean, the aspect ratio setting in the new xvid beta 3 ? Or the ar setting in mpeg files ?
Both are ignored by my players (ess+mediatek)

I mean xvid's AR settings.

You are right, i made a little test:

Changing Pixel Aspect ratio:
elta 8883 (MediaTek): ignored
Yamada 6100 (ESS): ignored

Setting Picture Aspect Ratio:
elta 8883 (MediaTek): ignored
Yamada 6100 (ESS): black picture, no sound

Would be nice to have support for these features, i could encode my dvb capture without resizing and i encode a lot anamorphic, but as they do not even read the ar settings of mpeg files...

I need this feature for the same reason: DVB captures.

How do you compare the playback quality of the two players?

How did you change the AR?

I changed it in the Xvid configuration to 16:9 PAL, i was trying to make an anamorphic encode.

I would say both players are equal in quality, i cant see a difference on my tv, but im not that quality freak...
Some people say the MediaTek chip uses some postprocessing, but i cannot see this with my elta.
Only reason why i bought the elta were the neverending problems with resizing and aspect ratio with the Yamada.
