I recently brought a DVR - digital video recorder - type device from Zazz, a one special per day online store.

It is powered by the Realtek RTD1261, aka the Realtek Venus. It's a 200MHz MIPS32 core '4KEc' V6.12, with a video encoder and decoder ASIC. My particular model also contians a combined DVB and Analog TV reciever.It has HDMI and Component output, optical and stereo audio out, as well as Composite+Stereo video input. There's an internal SATA HDD bay for recoriding and timeshifting, external USB port and SD card reader. It has a USB port for connectivity, and contians kernel modules for a Realtek USB WiFi device.

It runs a 2.6.12.6 kernel, uses ulibc as it's c library and busybox 1.1.3 for the majority of it's userland.

There is a telnet server running on the standard port, login: 'root', no password.

The manual for the device has been published by Zazz here. There is no mention in the manual, or on the website, of the GPL and/or how to aquire the sources to the GPL'd components in the device.

There is no source included with my device. There is no mention of source in the manual, nor on Zazz' website. Neither the packaging nor the device bears any identifying markings of an OEM or branding.

I have found some sources for devices that have similar internals, from other companies:
