SatelliteSale Audio Video 10-Pin RCA Composite DirecTV Replacement Cable PVC Black Cord 6 feet

Q: Will this satellitesale audio video 10-pin component cable work using it to connect my directv stream device with my yamaha av receiver htr-5240?

If by "DirecTV stream device" you mean then C71KW-400 then no. Seems like there are 2 video/audio output available. First one is an HDMI that can pass audio and video, second one is the optical cable that passes audio only. Unless your Yamaha receiver is very old you should have both HDMI and optical inputs available. For older models you must have at least an optical connection which still passes Dolby digital. We have optical cables for sale. Best, SatelliteSale.net Support Team

Q: On the genie hr54-200 can i use the hdmi to the tv and the audio from this to a receiver at the same time?

Yes, you can drive 2 devices from HR54 or any other DirecTV for that matter. DirecTV receivers send audio and video to all available outputs so connecting multiple devices is possible. Let us know if you have any additional questions. Best, SatelliteSale Team

Q: On the genie HR54-200 would this cable combination work at 50' length?

Shouldn't be a problem at 50 feet

Q: Does this work for Sega Genesis? The pins look similar

No this cable will not work with Sega Genesis. It's a DIRECTV only cable to convert the output from a Genie or mini genie to be used on an older TV that lacks HDMI.
