Hi,
With 2.6.16-rc1, it's recording no audio, and it's recording black-and-white noise on video. Wooo, it's getting worse.
$ uname -a Linux dancer64 2.6.16-rc1dancer-dirty #1 Wed Jan 18 08:11:24 JST 2006 x86_64 GNU/Linux
From the information that I've gathered so far it seems like: 1. bttv was rewritten to support v4l2 2. record via v4l2 is broken, v4l1 is not (xawtv works, mencoder broken.) I've heard mencoder should work with v4l1, but I have not yet confirmed.
bttv-cards.c:
[BTTV_BOARD_GVBCTV5PCI] = { .name = "IODATA GV-BCTV5/PCI", .video_inputs = 3, .audio_inputs = 1, .tuner = 0, .svhs = 2, .gpiomask = 0x0f0f80, .muxsel = {2, 3, 1, 0 }, .audiomux = {0x030000, 0x010000, 0, 0, 0x020000, 0}, .no_msp34xx = 1, .pll = PLL_28, .tuner_type = TUNER_PHILIPS_NTSC_M, .tuner_addr = ADDR_UNSET, .radio_addr = ADDR_UNSET, .audio_hook = gvbctv5pci_audio, .has_radio = 1, },
dmesg gives me an impression that this path is taken properly: bttv: driver version 0.9.16 loaded bttv: using 8 buffers with 2080k (520 pages) each for capture bttv: Bt8xx card found (0). bttv0: Bt878 (rev 17) at 0000:03:0b.0, irq: 22, latency: 64, mmio: 0xfdcff000 bttv0: detected: I-O Data Co.

v4l-info is dumped with:
printf("inputs\n"); for (i = 0;; i++) { memset(&input,0,sizeof(input)); input.index = i; if (-1 == ioctl(fd,VIDIOC_ENUMINPUT,&input)) break; printf(" VIDIOC_ENUMINPUT(%d)\n",i); print_struct(stdout,desc_v4l2_input,&input,"",tab); } printf("\n");
which is probably handled in bttv-driver.c:static int bttv_common_ioctls(struct bttv *btv, unsigned int cmd, void *arg)
which unconditionally sets: i->audioset = 0;
