Good morning,
I currently am using a first generation Hauppage bt878 card to do some
TV captures through my VCR. I use the composite1 input, and I'm using
streamer/mencoder to do my capture and encoding. (bttv card=10 tuner=0)
--dmesg snap--
bttv: driver version 0.7.104 loaded
bttv: using 4 buffers with 2080k (8320k total) for capture
bttv0: Bt878 (rev 2) at 00:0c.0, irq: 5, latency: 32, mmio: 0xdfdfe000
bttv0: detected: Hauppauge WinTV [card=10], PCI subsystem ID is 0070:13eb
bttv0: using: BT878(Hauppauge (bt878)) [card=10,insmod option]

bttv0: Hauppauge eeprom: model=38101, tuner=Philips FI1236 MK2 (2), radio=no
bttv0: using tuner=2
--dmesg snap--
When capturing at any resolution, the first six pixels on each line are
black. I have the same behavior in Windows using VDub with the
open-source bt8x8 driver and Hauppage's VFW and WDM drivers. When I use
VirtualDub, I use the little DLL-based tweaker that you can download for
it that will adjust the device registers to let you "recenter" the
image. This works well.
Are there any Linux resources to adjust the device registers on a bt878
to recenter the image? Do you guys/gals think my problem is stemming
from the fact that I'm using my VCR as a tuner through the Composite input?
Thanks much,
Phil
