Problem parsing pdb record entry in c#

[Ron]

Hi all,
I am creating a parser for a pdb taken from a palm device. Though I am having 
trouble reading the record entry List.
Everything works up to the point where I try to parse the record entry list.

Here's my code:
-------
    class RecordList
    {
        public UInt32 nextRecordListID;
        public UInt16 numRecords;
        public SortedList<UInt32, RecordEntry> recordEntries;
        public UInt16 placeHolderBytes;
        public RecordList(BinaryReader br)
        {
            nextRecordListID = br.ReadUInt32();
            numRecords = br.ReadUInt16();
            recordEntries = new SortedList<UInt32, RecordEntry>();
            Console.Out.WriteLine("NumRecords: "+numRecords+"; IDChunk:" + 
nextRecordListID);

            for (int i = 0; i < numRecords; i++)
            {
                RecordEntry ent = new RecordEntry(br);
                recordEntries.Add(ent.dataOffset,ent);
            }
            placeHolderBytes = br.ReadUInt16();
        }
....}

   class RecordEntry
    {
        public UInt32 dataOffset;
        public Byte attributes;
        public Byte[] uniqueID;
        public RecordEntry(BinaryReader br)
        {
            dataOffset = br.ReadUInt32();
            attributes = br.ReadByte();
            uniqueID = br.ReadBytes(3);
            Console.Out.WriteLine("Offset: " + dataOffset);
        }
    }
----------------------
I am parsing up to NumRecords fine... but for some reason I get huge numbers 
for my offsets. I think I'm inturpreting the offset wrong... but am not quite 
sure what to do.
NumRecords: 9; IDChunk:0
Offset: 1083703296
Offset: 1086324736
Offset: 1088946176
Offset: 1074135296
Offset: 1076101376
Offset: 1078067456
Offset: 1079116032
Offset: 1081082112
Offset: 1083048192

In the documentation it states:
typedef struct{
  LocalID localChunkID;
  UInt8attributes;
  UInt8uniqueID[3];
}RecordEntryType;

I'm not quite sure what LocalID is... I assumed it was just a UInt32. 
Though I think I may be wrong in doing this... how do I use the 4 bytes 
localChunkID to give me the offset of the data?

Thanks for your time.
