Hi,
Not yet an experienced developer here, still working on BSCmpE.
I have attempted to add long-awaited support for the ATI TV Wonder USB Edition
(NTSC) to usbvision. I have patches of what I've accomplished so far, but I'm
not yet able to test it due to a couple of issues, at least one of which appears
to be an outstanding bug from a few years ago (the "cannot change alternate
number to 1 (error=-22)" issue). The entry in usbvision-cards.c is based on a
similar Pinnacle and Hauppauge entries: the device looks like it might have been
a rebadged Hauppauge WinTV USB, but inside it has both the NT1004 and NT1005
bridges, SAA7113H input processor, and FI1236MK2 tuner (although none of the
supported devices use .tuner_type = TUNER_PHILIPS_NTSC).
I'm still researching what other programs to test this with (VLC? v4l-utils?)...
Christopher Chavez
