you typically record from /dev/video0

Check dmesg to see whether those devices are created when you insert the 
USB connector. The lines will typically also tell you what each device 
is for
Example from ivtv, which handles a HW MPEG encoder:
[   24.954081] Linux video capture interface: v2.00
[   25.672673] ivtv0: Registered device video0 for encoder MPG (4096 kB)
[   25.672738] ivtv0: Registered device video32 for encoder YUV (2048 kB)
[   25.672849] ivtv0: Registered device video24 for encoder PCM (320 kB)

So you would want to record from video0, in order to have nicely 
compressed video. You can specify the compression quality for this card.

as the Ion apparently gives raw video, you would use VLC or another tool 
to record and compress.

the reason that card is in this system, is to rip old PAL recordings to 
digital ;)

Good luck,
