I am running into two problems with dvgrab.
Camcorder: Canon Elura 100 (miniDV)
- dvgrab will intermittently not download the entire image (~1 hour video):
$ dvgrab -timestamp -size 0 -format raw
Found AV/C device with GUID 0x000085000110863c
Waiting for DV...
Capture Started
send oops
~ snip, deleted a whole bunch of 'send oops'
send oops
The size of the file varies each time I download from the Camcorder.
