Q: grey and white checkerboard screen using airplay when playing DVD from macBook pro

Didn't know how to add to my post.  VLC worked for the video but not audio (only a music track.) I assume I will have to use an audio cable through my stereo to get sound.

What about being able to mirror video but not audio using VCL?

I do get audio with checkerboard screen when using airplay mirroring with Apple DVD player. If VLC audioi works for others I'll have to figure out why it doesn't work for me.

Thanks

Was able to solve lack of audio by selecting airplay audio. New problem is that playback is very jerky on airplay while not a problem on computer. What should be the display settings?

the reading for my network at the highest is S/N 63%/13% dropping to 51/13 - (would  moving airport improve reception)

My neighbors two  networks are both 22/13 and another network is 18/13

I have no idea how to interpret thgese figures.

Would air parrot cure the problem?

Just got aff the phone with Apple support - the told me that Airplay mirroring will not work with the Apple DVD player.  I'm still stuck with why VLC video is choppy.  I tried to reset my Airport extreme channel using airport utility but no channel  numbers are displayed - apple support was no help. Can you help me with this?

Thanks,

Both articles are very clear and informative.  istumbler indicates that my neighbor's routers are both on channel 11 while I am on channel 1.  Knowing this, should I still experiment changing my channel setting?  also, AirParrot seems to greatly reduce but does not totally eliminate the choppy effect.

I think moving the router will also involve moving the modem both of which will have to be moved downstairs from the second story of my house.  What's the advisability of cutting into my cable modem line and hooking up a splitter?
