Playing XviD on stand-alone video players?

[Wintershade]

So my Dad just bought a new DVD player which supposedly supports DivX, HDMI and a lot of other fancy stuff. Nothing is said about XviD, though.

I understand DivX and XviD are both MPEG-4 compliant formats, so my question is - will this DVD player be able to playback any XviD videos? If so, how should I make the encodes?
Should I disable B-Frames, QPel, GMC, anything else? Which fourcc should I use? Which quantization matrices?
What does actually matter?

I'm using MeGUI, btw.

Thanks for the help.

The stickies in this forum (note- moved) should help answer those questions. It depends entirely on the chipset inside, which varies from model to model; some are 100% capable, some barely manage to run half of official divx movies. If it turns out to be a mediatek model, it'll play almost anything, and the MTK profiles in celtic druid's builds (http://ffdshow.faireal.net/mirror/XviD/) will disable anything it won't.

Commonly divx players will refuse to play files with b-frames and packed bitstream, obviously if you're making new ones disable it, for old ones see mpeg4modifier to rewrite them, as well as fourcc and userdata. (lossless)

As for quant matrices and other encoding quality options, the presets sticky in the xvid forum is the way to go imho.
