By the sounds of it, the mono audio has been multiplexed to 4 channels and they are slightly out of phase with each other which is causing the echo. Some have said to downmix to 2 channels if you can and others still are saying that it'll still be out of phase (echoey) but just coming out of 2 speakers instead of 4...
The video looks good, but very similar to the Grindhouse one.
There is apparently another company working on a release in the US so it might be worth waiting.
