yes, you probably have one bttv device with a number of inputs. you |
| 59 |
need to switch inputs. they are usually called TV, Composite, S-Video |
| 60 |
etc. If there is more than one composite they might be called |
| 61 |
Composite-1, Composite-2 etc |
| 62 |
|
| 63 |
On the other hand they may be audio inputs? 4 composite inputs is |
| 64 |
rather excessive I would have thought. |
| 65 |
|
| 66 |
By the way which package does v4lctl come in? |
