Also, if you're only recording the output of the wintv and not displaying it, the video card won't even care you're recording a show. Your sound card usually must have a line-in port (or internal line-in). Like I said, I use transcode or mencoder, but never tried MythTV. I schedule my recording using the 'at' command (see 'man at') and let cron do its stuff. Note that the 'atrun' command which is run by cron, is set to check jobs every 5 minutes, see /etc/crontab to change this. I wouldn't suggest getting below 5 minutes as this could slowdown your system, but instead start and end your recording job 5 minutes earlier and later. Hope this is of use to you, Nicolas. -- FreeBSD 7.0-CURRENT #13: Sat Mar 25 09:45:35 EST 2006 root@clk01a:/usr/obj/usr/src/sys/CLK01A PGP? : http://www.clkroot.net/security/nb_root.asc [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.2 (FreeBSD) iD8DBQBEJaze4wTBlvcsbJURAmMlAKCI/DuzXB1JyDxm9u/wrSzUcLOYlACfQZyT j4TMU4VuAJTNsczni6RVBFQ= =w7+p -----END PGP SIGNATURE-----
