Release notes for bttv======================You'll need at least these config options for bttv:	CONFIG_I2C=m	CONFIG_I2C_ALGOBIT=m	CONFIG_VIDEO_DEV=mThe latest bttv version is available from http://bytesex.org/bttv/Make bttv work with your card-----------------------------Just try "modprobe bttv" and see if that works.If it doesn't bttv likely could not autodetect your card and needs someinsmod options.  The most important insmod option for bttv is "card=n"to select the correct card type.  If you get video but no sound you'vevery likely specified the wrong (or no) card type.  A list of supportedcards is in CARDLIST.bttvIf bttv takes very long to load (happens sometimes with the cheapcards which have no tuner), try adding this to your modprobe.conf:	options i2c-algo-bit bit_test=1For the WinTV/PVR you need one firmware file from the driver CD:hcwamc.rbf.  The file is in the pvr45xxx.exe archive (self-extractingzip file, unzip can unpack it).  Put it into the /etc/pvr directory oruse the firm_altera=<path> insmod option to point the driver to thelocation of the file.If your card isn't listed in CARDLIST.bttv or if you have trouble makingaudio work, you should read the Sound-FAQ.Autodetecting cards-------------------bttv uses the PCI Subsystem ID to autodetect the card type.  lspci liststhe Subsystem ID in the second line, looks like this:00:0a.0 Multimedia video controller: Brooktree Corporation Bt878 (rev 02)        Subsystem: Hauppauge computer works Inc. WinTV/GO        Flags: bus master, medium devsel, latency 32, IRQ 5        Memory at e2000000 (32-bit, prefetchable) [size=4K]only bt878-based cards can have a subsystem ID (which does not meanthat every card really has one).  bt848 cards can't have a SubsystemID and therefore can't be autodetected.  There is a list with the ID'sin bttv-cards.c (in case you are intrested or want to mail patcheswith updates).Still doesn't work?-------------------I do NOT have a lab with 30+ different grabber boards and aPAL/NTSC/SECAM test signal generator at home, so I often can'treproduce your problems.  This makes debugging very difficult for me.If you have some knowledge and spare time, please try to fix thisyourself (patches very welcome of course...)  You know: The linuxslogan is "Do it yourself".There is a mailing list: video4linux-list@redhat.com.https://listman.redhat.com/mailman/listinfo/video4linux-listIf you have trouble with some specific TV card, try to ask thereinstead of mailing me directly.  The chance that someone with thesame card listens there is much higher...For problems with sound:  There are alot of different systems usedfor TV sound all over the world.  And there are also different chipswhich decode the audio signal.  Reports about sound problems ("stereodoes'nt work") are pretty useless unless you include some detailsabout your hardware and the TV sound scheme used in your country (orat least the country you are living in).Finally: If you mail some patches for bttv around the world (tolinux-kernel/Alan/Linus/...), please Cc: me.Have fun with bttv,  Gerd--Gerd Knorr <kraxel@bytesex.org>
