Having a slight problem with ivtv-0.4.0, details below. ivtv-0.3.8 was
good (except ivtv-fb didn't work) and I've just reinstalled 0.3.8 and it
still works.
/usr/bin/ivtvctl --device=/dev/video0 -u 0xff
Segmentation fault
BTW any chance of adding which video devices get registered to the ivtv
driver to the dmesg log; helpful when there are multiple cards?
TIA
Duncan
