cannot capture video with my WinTV USB2

Hello,

I used to capture video using Ubuntu Edgy and a WintV USB2 framegrabber attached to a Canon VCC5 camera.
However, I upgraded two days ago to Feisty and now I only see static.

Running xawtv I see the following output:
xawtv -nodga
This is xawtv-3.95.dfsg.1, running on Linux/i686 (2.6.20-16-386)
X Error of failed request: XF86DGANoDirectVideoMode
  Major opcode of failed request: 136 (XFree86-DGA)
  Minor opcode of failed request: 1 (XF86DGAGetVideoLL)
  Serial number of failed request: 13
  Current serial number in output stream: 13
v4l-conf had some trouble, trying to continue anyway
Warning: Cannot convert string "-*-ledfixed-medium-r-*--39-*-*-*-c-*-*-*" to type FontStruct

with v4l-info I get the following:
