What settings should I use to export xvid for an old DVD player?

Those players are fussy, and the files that fail usually have something the player's chip can't handle rather than being too big. What's worked for me: - AVI container, Xvid video, MP3 audio (128-192k, stereo). AAC or AC3 audio is a common reason a file shows unsupported. - Resolution no higher than DVD: 720x576 if you're in a PAL country, 720x480 for NTSC. Keep the aspect ratio, so widescreen phone footage ends up something like 720x400. - Video bitrate around 1500-2500 kbps. Most of these players choke somewhere above 4000. - Turn OFF qpel and GMC. Keep B-frames at 1 or 2. If your encoder has a "Home theater" or DivX-compatible profile, pick that, it sets these for you. Also keep frame rate the same as the source, 25 or 30. Phone videos recorded at 60fps are another one that fails.
