[mythtv-users] pvr350 TV-out howto problems..

[Dan]

so I tried that, ..dd returns

# dd if=/dev/video/video0 of=/dev/video/video16 bs=64k
dd: reading `/dev/video/video0': Is a directory
0+0 records in
0+0 records out

note: /dev/video/ls -l

Dan,

forgot this.  Try running:

/usr/local/test_ioctl -u 0x3000 (for NTSC) or 
/usr/local/test_ioctl -u 0xFF (for PAL, I think)
then
/usr/local/test_ioctl -p 4 (for input from the tuner, I think) or
/usr/local/test_ioctl -p 6 (for input from s-video)

then

dd if=/dev/video/video0 of=/dev/video/video16 bs=64k

Does that work?

If not, try:

dd if=/dev/video/video1 of=/dev/video/video16 bs=64k

Run this as root (for now) just to be sure it's not a permissions issue.
