Command line driving me insane

[AeitZean]

I'm trying to save my Ezcap116 input to a file, from the command line. I've only got the video hooked up because that's all I want. I'm trying to record in 1 hour chunks, using a batch file to relaunch vlc every hour. the problem is my command uses --run-time=3600 --stop-time=3600 vlc://quit

when I run get_time from the rc interface, it always gives me a much larger number than it should (like 1371 after ten seconds or so), like it doesn't reset after the first time its run, it accumulates. any idea's why its doing this? any clue how to reset the time at the start of a recording?

is it something to do with my input device?

any help would be appreciated, I'm at my wits end.

thanks

edit: also, if I use run-time=60 and stop-time=60 (ie one minute) it crashes out instantly with "idummy demux: command quit"
