help
Support for external IEEE1394 adapters designed by Digital Everywhere and
produced by El Gato, shipped under the brand name 'FireDTV/FloppyDTV'.
These devices don't have a MPEG decoder built in, so you need
an external software decoder to watch TV.
Say Y if you own such a device and want to use it.
