Did you buy a CD burning package with the intention of making VideoCDs, only to find out when you get it home that it doesn't come with an encoder to turn your avi files into mpeg files so you can actually make VideoCDs? Then avi2vcd is what you need.
Avi2vcd is an MPEG encoder with only one purpose: encoding VideoCD 2.0 compliant MPEG streams. Avi2vcd can create all 3 valid VideoCD streams: FILM (23.976 fps), PAL (25 fps), and NTSC (29.97 fps). The horizontal resolution must be 768 pixels or less, the vertical resolution must be 576 pixels or less. Audio need not even be present, and if it is, can be stereo or mono, 8 or 16 bit.
If your source video is longer than can fit on one CD, than avi2vcd can split it into multiple MPGs during encode. It can also shut your PC down for you when it's finished encoding.
Please note: You can't just copy the mpeg file avi2vcd (or any other mpeg encoder for that matter) produces to a disc and expect it to play in a DVD player. You still need to use an appropriate VideoCD recording application that explicitly supports VideoCD to actually create the VideoCD disc!
