Hauppauge WinTV-NOVA-T PCI
The WinTV-Nova brand is used by Hauppauge for their decoderless digital TV PCI cards. The -T suffix means DVB-T. There have been two different types of card sold under the name WinTV-NOVA-T PCI.
Original Version
The first version (before about July 2004) was based on the SAA7146 interface chip and either a TDA10046 or a TDA10045 or an LSI L64781 demodulator.
All of them are well-supported. Due to the limitations of the quite old-fashioned hardware there may exist some quirks when using multiple cards in a system. Tuning is slower than in competing designs.
In most systems and for average users these cards work satisfactorily, the Linux drivers are well-tested and robust.
The earliest cards with LSI demodulators work "out of the box". For TDA tuners, you need to identify your chip and see the TDA10045 or the TDA10046 pages. Since there doesn't appear to be a way to tell which one you have programatically you'll probably have to take the card out and look.
New Version
This model is based on a Conexant cx2388x. Works "out of the box" with kernels 2.6.12 onwards.
