Xailer & OZ Software

I have just bought Xailer Professional and am very much thrilled with the
product. I was flattened by the performace of the sample project
SamplesDataControlsDBFData6. I find it difficult to rebuild the same
myself. Is there any Video tutorial or something similar which can show me
how to build the same ?
This can prove to be a great boon to me.
Kindly point me to advanced tutorial (the one on xailer.com are primary
ones)
TIA
Milan.
