[Beds] Re: dv2jpg compilation (and various video questions...) - UPDATE

[Darren Parkinson]

Well, it seems I managed to get dv2jpg to compile by trying every version of
libdv available, even though the docs say to use 0.4... ho hum.

Unfortunately, this doesn't cure my problem. dv2jpg has the same problem --
it can read my original avi file, but not the new one. If I "file" both,
they produce the following output, which is a bit odd!!

Any thoughts welcome... thanks...

Can open with avidemux:
tempfile.avi: RIFF (little-endian) data, AVI, 720 x 576, 25.00 fps, video:,
audio: uncompressed PCM (stereo, 32000 Hz)

Cannot open with avidemux or dv2jpg:
Movie.avi: RIFF (little-endian) data, AVI, 0 x 0, 25.00 fps,
