gst/dvdlpcmdec/gstdvdlpcmdec.c: If an incoming timestamp is within one sample of our current timestamp, then keep it....

Browse source 
Original commit message from CVS:
* gst/dvdlpcmdec/gstdvdlpcmdec.c: (update_timestamps):
If an incoming timestamp is within one sample of our current
timestamp, then keep it. This prevents imprecision in the
PTS (which only has 90khz granularity) from affecting our stream.
