It's actually easier to watch movies on your Treo for Mac users. The first thing you'll need is
TCPMP. This is the excellent freeware player that you'll need to install on your Treo. From there you'll need a codec for MPEG 4 files.
The next step is to get the movies to your Treo. For this, you'll want to download
Handbrake. If you insert a DVD, you'll be able to covert to an MPEG 4 file for use on your Treo.
Here are my settings for Handbrake:
Handbrake Settings:
320x128 for widescreen DVD Settings

Copy the file to your SD card, open up The Core Pocket Media Player and off you go.
