that's the self-defined -EBUFFEROVERFLOW in old versions of the DVB 
driver and in the Metzler-source. Please use a recent driver and you 
should get -EOVERFLOW which is correctly recognized by the libc.

Whenever you get this error code an internal ringbuffer overflow 
occured. You can avoid this by collecting your data fast enough and 
optimizing the buffer size using the DMX_SET_BUFFER_SIZE ioctl.

But in most situations this error is not critical anyway, you can safely 
ignore it. DVB section data is always transmitted repetitive.
