The buffer is RAM that holds a number of frames decoded in advance of you actually seeing them. If the buffer is running out, it means that your system isn't decoding faster than you are seeing the frames, either because your system isn't fast enough, the codec is too complicated, or there are too many simultaneous streams.

The only potential solutions is the inverse of these potential causes. Either a faster system, simpler codec, or fewer streams. The faster system and fewer streams is pretty self explanatory, but there are a couple of options for the simpler codec. You can transcode the video to something like HQ/X before starting the edit or use proxy mode, both of which use I-frame codecs, simplifying the decode math required during playback, instead of long GOP codecs that many cameras shoot, edit in a lower resolution project setting, or if you have the Edius WG, use the viewer resolution drop down to reduce to 1/2 or 1/4. The latter 2 essentially tell edius that it can draw/display less data than is in the actual file.
