When I attempt to play the pond.dv file I see this,

[lukas@sto-lknutsson libdv]$ ./playdv ../pond.dv 
Audio is 44.1 kHz, 16 bits linear quantization, 2 channels
Xlib:  extension "XVideo" missing on display ":0.0".
Xlib:  extension "XVideo" missing on display ":0.0".
 Using gtk for display
Displayed 915 frames in 29.86 seconds (30.65 fps)

pretty good except I didn't see anything in the window, but I did hear
the soundtrack.

I created a video using encode but I couldn't watch it at all. 

[lukas@sto-lknutsson libdv]$ ./playdv ~/src/intf/data/intf.dv 
Xlib:  extension "XVideo" missing on display ":0.0".
Xlib:  extension "XVideo" missing on display ":0.0".

soundcard doesn't support stereo
Displayed 50 frames in 00.00 seconds (102669.40 fps)

Funny encode doesn't even create a soundtrack. I am using the latest
stuff from CVS. I then did a ./configure --disable-xv but nothing
changed. In fact it still seemed to check for xv support,

[lukas@sto-lknutsson libdv]$ ./playdv ../pond.dv
