Looking for a V4L2 recording software (with sound and GUI)

I want to record avi- or mpg-videos from:

  1. my WebCam
  2. my PVR (Plextor ConvertX PX-TV402U)

Both are providing video data from /dev/video
(ConvertX: and audio from /dev/dsp).

For the webcam i first tried “luvcview”,
but it hasn’t got enough features and for
the ConvertX i checked out “mythtv”, but
this is too komplex for my demands.
I also tried screen capture software
(“xvidcap” and “recordmydesktop”), because
i can watch both device’s output with VLC.
(KMPlayer wasn’t able to show output!)

Isn’t there such an easy-to-use like VLC,
that can record video and optionally audio
and is maybe available in a repo, too ?

Thank you all in advance
