Cool, thanks Pierre!

I mean, this is real bug, not just end result of my hacking around :}

I think Kino identified this file as AVI DV, type 1, ODML.
Type 2 plays ok even if 3Gb+. Type 1, IIRC has just raw DV stream 
encapsulated in AVI, without specific real audio track, because audio
 and video already exist in single DV stream.

I wonder a bit if Cin-GG can do auto-clip feature like Kino? 
When Kino makes clips out of single file probably by using
embedded by camera timecode stamps/gaps between them.

On modern Linux Kino should be run via oss emulation layer, like aoss, or
something similar for Pulseaudio (I use ALSA only).

Also, backward playback (witch 16Mb default cache in CinGG) 
even for simple DV file is slow.
Not sure if it can be speed up without major re-engineering of code ...
