Hi, I have added capture mode to Amancio's great "tv: program. Requires you have installed libjpeg to compile. Just press enter on the xterm to save frames to files named "imgXXX.jpg" in the same directory (XXX is a counter). You can find it (sources only) at http://www.iet.unipi.it/~luigi/lrtv.tgz Note that I have slightly changed the code to grab single fields as opposed to full frames. On a TV, even and odd fields are averaged, but on a video capture board they are not. For moving scenes, you see two intermixed images with a very bad visual effect. Now if someone who is X-literate can make it work easily at least on 16bpp screens... This requires remapping the color table because the meteor uses 5-5-5 bits per color, while video boards (at least my S3) has a 5-6-5 bits per color (RGB).
