Hi Hans, I'm trying to use a USB stick that I just bought. (http://linuxtv.org/wiki/index.php/Pinnacle_PCTV_HD_Stick_(801eSE)) It works perfectly under Linux (Arch Linux's 2.6.35). Webcamd sees it, and it seems to almost work: # usbconfig -u 4 -a 2 dump_device_desc ugen4.2: <PCTV 801e YUANRD> at usbus4, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON bLength = 0x0012 bDescriptorType = 0x0001 bcdUSB = 0x0200 bDeviceClass = 0x0000 bDeviceSubClass = 0x0000 bDeviceProtocol = 0x0000 bMaxPacketSize0 = 0x0040 idVendor = 0x2304 idProduct = 0x023a bcdDevice = 0x0100 iManufacturer = 0x0001 <YUANRD> iProduct = 0x0002 <PCTV 801e> iSerialNumber = 0x0003 <01008D3B7A> bNumConfigurations = 0x0001 # webcamd <...> dvb-usb: found a 'Pinnacle PCTV HD Pro USB Stick' in warm state. dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.

Eg, a tool like "azap" does not show any "uncorrectable errors", but the stream itself is pixelated / corrupt enough to crash mplayer. I can see just enough of the picture to tell that I'm tuned to the correct station. I'm not sure if this is a tuning issue, or a USB issue or what is going on. I also do not see the s5h1411_readreg and dib0700 errors on linux. These errors do not happen all the time on FreeBSD either. But the stream is always corrupt. This is on a fairly beefy machine (Xeon 5150 @ 2.66GHz) which can easily sustain 20Gb/s through its PCIe bus (its one of my 10GbE testing machines in my home lab).. I'm running 9-current as of last weekend, with witness/diagnostic disabled. I'm running webcamd pulled from your svn as of this evening. A ~2 week old build also shows the same issue. Can you offer any advice as to how to debug this? Thanks, Drew PS: One more bit of info -- when I ^C test_dvr, it hangs. I have to ^C webcamd itself to get azap & test_dvr to exit.
