Compact Flash Player - Problems with DivX video

[Mojo2000]

I'm currently trying to install a number of compact flash players into a system for someone, and am having a few problems.

The CF Player is this - http://www.pixels.uk.com/products/MedeaWiz/DV68.htm

It should play MPEG-4, MPEG-2, MPEG-1, JPEG and MP3 digital media.

So I have a number of DVD's to transfer to these CF cards. I have ripped all the necessary VOB files off the DVD, and changed the extension to mpg. The video plays fine on a PC, but when I put them on the CF player the video looks great but the audio doesn't play. It looks like the MPEG2 videos have embedded AC3 audio - not recognised by player.

Essentially, as I want to lose as little quality as poss, I want to change this audio to MP3 (as MP2 audio seems to have problems too).

I used Dr DivX to encode to MPEG4, with the quality set to 'Insane Quality', then in advanced I set the bitrate to 4000kbps (2-pass), and the audio to 224kbps mp3. The video looks and sounds fantastic on my PC, but when I put in on the player the video pixelates every few seconds and the audio skips at the same time.

Any ideas what else I could try? Ultimately I would rather not have the DivX watermark at the bottom, I want to keep as much quality as possible, and only really need to change the audio to mp3 format.

Thanks in advance!

It sounds like bitrate peaks are getting too high for your device. Use a lower average bitrate and/or one of the Divx profiles to limit the peaks. Xvid has more profiles to choose from (and you can see what the limits are).

That page you link too includes a CF card with a 1GB capacity and says it will hold 1 hour of mpeg-4. That puts the bitrate at a little over 2k, or about half the bitrate you are currently using. At 540 x 480, 2k is easily enough.
