Folks, announcing the release of Lplex 0.2 Beta, a simple drag-and-drop open-source win32 console utility intended to provide a free, quick, and hopefully painless way to
  • create a playable full-resolution "audio-only" dvd-video disc from
    wave or flac audio filesets, with md5 verification and archival
    content.
  • extract unencrypted lpcm audio streams from dvd-video to wave or
    flac in an md5-verified process.
2006-08-08 : Version 0.2 beta released
Please take a moment to look at the changelog and updated readme.

Shifty, it could be that the pops are upsampled cd-audio SBEs.

I tried to replicate your situtation by taking a 30-second 16/44 wav snippet and cutting it at random into three sample-aligned files (using the EAC sound editor), and verified the presence of SBE errors using shntool. Then I authored and extracted a cd-audio image to get a set of extracted wavs with SBE errors.

I upsampled both the original and the SBE set to 16/48 using SRCdrop and authored a 2 title PAL 'seamless backward' mode dvd.

In Audacity I captured the playback of both the original anf the SBE set, and then the corresponding playback from the dvd. The waveforms for the source, and the dvd are exactly the same . The original set has no pop. the SBE set has a faint pop which is present on the extracted wavs and naturally carries through to the dvd.

This was the only way I could get any sort of pop, so the question now is are you sure your cd-audio sources don't contain SBE errors, and do you get pops with non cd-audio sources?
