I have managed to get saa7134-dvb to load the zl10353 frontend but I
can't get the analog tuner or the digital tuners working. I don't even
know what they are.
i2c scans show up the the following addresses:
0x61
0x62
0x63
0x68
And the windows driver contains the following strings: (This may be a
universal driver though because I don't think all these are present)
D64083
SAA6752
TDA9885
TDA8262
TDA8275A
TDA10046
I really don't know what I am doing so if anyone has any suggestions
they would be most welcome.
Also, If anyone knows of a tuner which comes in the 36mm x 26mm x 5mm
metal case that might help narrow down what might be inside.
