From 997940c5b22eab62f570dcd410179b8a60f1ad84 Mon Sep 17 00:00:00 2001 From: Steven Toth Date: Sat, 13 Sep 2008 15:56:34 -0400 Subject: S2API: Changed bandwidth to be expressed in HZ From: Steven Toth Also added some compat code for the older API. Added more ISDB message/command suggestions, current not connected in dvb-core.
