A Word about MPEG-4

Together, this version of the ConvertX and WinDVD Creator support
two types of MPEG-4 compression:
• Real-time MPEG-4 (ISO) compression, with file extension .mpg, is
supported by the ConvertX.
• MPEG-4 (DivX) compression, file extension .avi, is supported by
WinDVD Creator through a software encoder.
There are some differences in how you use these formats. For input, the
ConvertX hardware encoder can capture video and compress it using the
MPEG-4 (ISO) standard, saving valuable space on your hard disk. You
can play this MPEG-4 video and view it on your computer using the
WinDVD 4 player. You cannot edit it or convert it into another format.
For output, WinDVD Creator software includes a DivX software coder-
decoder, or "codec." So you can take uncompressed video, or MPEG-1
or MPEG-2 video, edit this video, and output it in the compressed
MPEG 4 (DivX) format. DivX compressed video is a popular format,
and is playable with Windows Media Player with a DivX decoder (see
http://www.divx.com/) and with other decoders available on the Internet.
