 Hello!

 I'm trying to use the "quickdnr" filter. When I enter LiveTv or when I
 want to watch a recording, mythfrontend dies and gives me an "illegal
 instruction" error.

 From what I understand by looking at the docs and reading the source, it
 is important that my CPU supports SSE or MMX. This is a Pentium 3 with
 450mhz and /proc/cpuinfo tells me that it supports both. I've tried a few
 things like compiling MythTV with --march=i686 or --march=pentium3, but it
 happens all the time.

 I'm quite sure that filter_quickdnr.c gets compiled properly (with MMX, I
 mean) because an "#warning HELLO!" yields the expected result when put in
 the "#ifdev MMX" section.

 I don't know if this is just a problem with my setup, maybe it's related
 to some hardware brokenness. If this is the case, please disregard this
 ticket. Otherwise, I'll be very happy to provide additional information
 when necessary and test patches.

 Regards,
 Michael "laga" Haas
