Ok, I finally got my HVR-1950's to work! First, I downloaded the firmware files [http://www.isely.net/pvrusb2/setup.html#Firmware] to '/usr/syno/hotplug/firmware' on my DS213. Then I downloaded ‘gcc421_glibc25_88f6281-GPL.tgz’ and ‘synogpl-2636-6281.tbz’ [http://sourceforge.net/projects/dsgpl/files]. Then I followed these instructions [http://hallard.me/how-to-install-kernel-modules-on-synology-ds1010-dsm-4-1] and was able to do a ‘make menuconfig’. I went to “Device Drivers” and selected “Multimedia Support”. I then selected “Video For Linux” and chose "Customize analog and hybrid tuner modules to build". I made sure that everything was selected in that section and exited back to the previous section. Then I chose “Video Capture Adapters” and selected “Conexant cx23416/cx23415 MPEG encoder/decoder support”. I then selected “V4L USB devices” and chose “USB Video Class (UVC)”, “Hauppage WinTV-PVR USB2 support”, and "Conexant cx231xx USB video capture support". After exiting the menu and saving the configuration, I did a ‘make modules’ which successfully finished and built all of the KO files. I then copied all of the KO files under the ‘media’ folder (except for the i2c files which were located in the 'i2c' folder under drivers) and subfolders over to the ‘/opt/lib/modules/2.6.32′ folder on my DS213. I did a ‘mknod /dev/video0 c 81 0′ and a ‘mknod /dev/video1 c 81 1′ and then an ‘insmod’ for the following files in this order:
insmod i2c-core.ko
insmod i2c-algo-bit.ko
