I'm presuming this is automatic as, so far, I haven't found a way to try and adjust it upwards.. The 12fps is strange, again to me, as I thought it had to be 29?, near 30, for NTSC..

I didn't know that mencoder would grab streaming video and when I man mencoder I get mplayer's man text.. Most of the acronyms are strange to me too.. I've purchased two books on multimedia, sight unseen, and they are both "click this, click that," Fooey.. Running tops whilst recording I get average loads around 0.11 and CPU SYS around 3.7%.. Even that doesn't sound right to me... I have 512mB SDRAM and a 1gB swap partition, never, seemingly, used... Xawtv doesn't have many actual settings except I have to change the PAL default to NTSC, of course and enter the input jack in the rc file.. I use both composite1 or SVideo... Merely invoking xawtv in an xterm and right clicking on the blue video window, I can click on capture /or/ use the shortcut, thence select AVI, thence enter a single filename & click on the record bar, a toggle.. The picture disappears during recording; a small inconvenience so far using the sound as a reference, and I get a running red text report of what's going on.. So far I don't know what most of them are..
