Sundtek Support Forum

Dear Sundtek Support team,

I am wondering if the binary driver is compatible with older hardware like the VIA C3 processor!?

On my system (VIA C3, soldered on Epia-M6000 board) the VDR process quits with "illegal instuction".
The instruction set of the C3 processor is very limited (uses 586 (not 686), no SSE, ...).
Using a typical Hauppauge DVB-T USB receiver I can smootly run a headless VDR on my freshly compiled gentoo linux on my C3 with 128MB ram. But when I replace the DVB-T device by the Sundtek MediaPro USB device, then VDR quits with "illegal instruction". The driver (current version as provided by the first post in this thread) seems to install neatly (32bit):
------------------------------------------------------------------------

So what could be the problem with the Sundtek driver? Could you provide a driver with a "legacy" instruction set like 386 or 586 w/o SSE?

Here are the specs of the C3 processor: cat /proc/cpuinfo
