Provideo seems to make PCI and PCIe capture cards for DVR applications.
PV-981
The PV-981 is a 16-port capture card, with four BT878 chips, each wired to 4 inputs. It also has four audio codecs on board (not yet tested/documented) and some GPIO (likewise).
It's misdetected as a PV150A, which has apparently never been a valid Provideo part number, and nobody seems to know why, see this thread.
To enable all 4 inputs:
rmmod bttv modprobe bttv card=77,77,77,77
That's it, now it's a generic 4-input card with no audio or s-video, if you need audio then you'll have to pick a different card to pretend to be.

Inputs
While misdetected as a PV150A, each of the 4 chips can be switched between input 0 and input 1, as highlighted in the following image:
Attempting to select input 2 or 3 crashes VLC. Fix your modprobe settings as detailed above, and suddenly it works!
Pinout
The DE-15 connectors (high-density, looks like VGA) on the back of the card have the following pinout:
1 blue 1 2 blue 2 3 ground 4 blue 3 5 blue 4 6 green 1 7 green 2 8 ground 9 green 3 10 green 4 11 red 1 12 red 2 13 ground 14 red 3 15 red 4
If this cable is plugged into connector 1, the "blue" and "green" cables are the video inputs, and the "red" connectors are audio.
If this cable is plugged into connector 2, the "blue" and "green" cables are the video inputs, and the "red" connectors do nothing.
There are 4 small headers and one large one, there are also two 2-pin connectors and the unpopulated footprint for a molex power connector.
OP1, OP2, OP3, and OP4 have the following pinout:
1 ??? 2 ??? 3 ground 4 ground 5 ??? 6 ??? 7 ground 8 ground 9 ground 10 ground
GP1 has the following pinout:
1 ??? 2 ground 3 ??? 4 ground 5 ??? 6 ground 7 ??? 8 ground 9 ??? 10 ground 11 ??? 12 ground 13 ??? 14 ground 15 ??? 16 ground 17 ground 18 ??? 19 ground 20 ??? 21 ground 22 ??? 23 ground 24 ??? 25 ground 26 ??? 27 ground 28 ??? 29 ground 30 ??? 31 ground 32 ??? 33 ??? 34 ???
J1 has the following pinout:
1 ??? 2 ???
J2 has the following pinout
1 ??? 2 ???
Chips
U11, U15, U18, and U21 are 24c02 2-wire eeprom chips and contain the identification number that bttv uses to detect the card (there are 4, one for each bt878), on this card the numbers should be for the PV150A (according to the bttv source code) and if you change them to the ones for the PV143 you will then autodetect the card as having 16 inputs.
Snippet from bttv-cards.c:

232 { 0x1463aa03, BTTV_BOARD_PV150, "Provideo PV150A-4" },
The audio chips U23-U26 are TI AIC23B stereo codecs, use of them is not defined yet.
