Ok I just got me an AverMedia Tv Series Framegrabber it has a Bt 878 and a tuner and on the PCI board There is a sticker on the tuner with the following checkboxes: N N-j P-N P-M PBG PDK PI SDK BG + DK SL N is the only one checked ! it also has 74HC4052 (logic?) one PIC16C54A (MC?) one 24LC02B (Serial EEPROM) and whatever is inside the tuner case ok thats a TDA9800T a SA5523 and a TBA5737M all from Philips I was greping around for bttv on my system and its nice the installation allrady put it in for me and recognised the BT chip (/var/log/messages) I installed xawtv All runs without apparent error messages ... However for one the noise that xawtv shows me is repetetive and not all of the screen really changes when I am flipping around the channels And the blue in the composite setting is pure and static (even though I had verified that the attached ntsc cmos Cam works fine from Windos) the use of this cam (or better a CCD version) is the whole reason for me doing this investigation ! I figure it must be because one of the readme files (kerneldoc/v4l/bttv/INSTALL) says I have to edit a Makefile and put a 6 in there for Avermedia ? (I looked at that file in the 'drivers' Subfolder of my kernel and found no indication what they may be talking about ...) I cant believe thats how its supposed to be done why not use conf.modules ??? right now it only mentions alias char-major-81 bttv Sorry i havent found any better documentation :( what I have is the stuff that apparently came with my 2.2.15 kernel original from the Mandrake 7.1 install and also what came with xawtv And right now as I am typing the LAN is down I think I am missing some simple point here by not having a clue where to start reading those docs or having some outdated ones ??? Any hints ? Thanks Tobias
