Actually, I hvan't heard of a brooktree 484 card, don't you mean 848? Seriously, if the card is using the supplied BT driver from FreeBSD, then you have the luxury of using any of the BT chipsets (878 is popular and readily available). Failing that, it really depends on how your application is accessing the capture device. If it is just copying data from the raw device, then you can use the Hauppauge PVR series cards which I absolutely love, having used them in a surveillance application myself recently. IF the card you are looking at really is the 848 chipset, then you should be able to use any of the brooktree cards without needing to change the driver at all. Snippet from the /usr/src/sys/dev/bktr/bktr_tuner.h file ---------- * This is part of the Driver for Video Capture Cards (Frame grabbers) * and TV Tuner cards using the Brooktree Bt848, Bt848A, Bt849A, Bt878, Bt879 * chipset. ---------- Cheers & good luck Tim -- Tim Aslat Spyderweb Consulting http://www.spyderweb.com.au Phone: +61 0401088479
