I have a 150fps 16 channel H264 hardware encoder card,

I modified bc-record.c for PAL:

```
vparm.parm.capture.timeperframe.denominator = 25;
vparm.parm.capture.timeperframe.numerator = 1;
vfmt.fmt.pix.width = 704;
vfmt.fmt.pix.height = 576;
```

I can open up to 5 /dev/video devices either with bc-record or with cat, but if I try to open a sixth, I get:

cat: error reading `/dev/video6': Device or resource busy

Why is this?

5 channels make a total of 125fps - even if I have:

```
vparm.parm.capture.timeperframe.denominator = 10;
vparm.parm.capture.timeperframe.numerator = 1;
```

Which is 10fps I believe? - I still cannot open more than 5 channels without getting "device or resource busy"

Any ideas?
