That's since the card is a bttv based card from Twinhan, the original 
card (DVB-S) featuring a tuner from LG, and the tuner was called LG DST 
Tuner, and hence Twinhan people referred the "card", not the MCU or the 
tuner,  internally in their driver as DST, standing for (D)igital 
(S)atellite (T)uner.

The Twinhan company was originally, VVMER, then they changed there 
company name to Twinhan, and their DVB PCI product range to Visionplus. 
But, i would say the Visionplus would be more meaningful, as earlier 
they did not have any EEPROMS having PCIID's. Now all the older cards 
without EEPROM's are considered obsolete, and all new cards would 
feature an EEPROM, and the Visionplus product range has a PCIID 1822.

And in this case, when they change a product range, it would be easier 
identifying the product range.

So when Jamie was reverse engineering the driver, he gave the originally 
referred name.

It does not make a difference what it is called, The point was to remove 
the "-T" which was a bit misleading. It can be changed to anything that 
looks better. Well, i conveyed the point accross.
