Hi all,
I'm new to this forum but it seems the last place remained to get an help about mastering for a dvd. I'm usual to mastering (both in digital and analog domains), mainly rock or ambient music, but I've now a strange problem with a DVD.

The audio part of this DVD was mastered in studio, all perfect, peaks at -3dbfs when passed in digital, only a few compression, not the classic 'saucer' waveform.

All is good when playing on computer or stereo, there's no digital clip or noises. On some 'home theater' systems I get the audio signal 'saturating' the inputs of the amplifier, in an 'analog' way, nothing digital, even if the dvd player is connected with a digital cable.

The saturated signal is not when it's hotter with leve, it begin saturating when there are 'peaks' of frequencies, in particular mids.

If I listen via headphones 'before' the amplifier all is good, after the amplifier it gets saturated with passages containing high saturation levels on some mid frequencies (but nothing over 0dBFS, and no digital clipping/distortion).

If I lower the overall level of audio tracks by -6 or -8 db, saturation disappear in most of passages.

Any idea?

Don't realy know anything about mastering DVD's but a lot of music DVD'd I buy (AC/DC live at Donningham, VanHalen Right here, Right now, Queensryches the art of live to name a few) have that similer sound when I watch them on my Playstation. They work fine on the bedroom dvd player but thats pretty new. Could be something due to Authering? or Zone type thing. Probly not much help but I just thought I'd throw that up about proffetional DVDs having a similer delema.

I've heard amps to weird things in low-voltage situations (and other amps not bat and eye in the same outlet). is the wall outlet providing the required power?
