Been making test DVDs using Sound Forge to set sinewave levels - this is then Edited in Movie Studio, with Text to identify the Level and the Frequency when this is played back it sounds OK, although watching is somewhat tedious. The maximum level is minus 3.5 dB.
However, recently I've noticed the Rendered m2ts files are quite good at the low frequency end (even 15Hz). . . . . . yet when converted to DVD it appears as though the LF is either lost - or significantly lower level.
The same TV is used to view the Vids, via HDMI and the speakers are separately amplified from the TV
The DVD is replayed using a Philips 3D DVD player . . . .
Can anyone suggest why this LF loss might be? I thought that DVD's would be somewhat similar to CD's ( Although I know the CD was developed for HiFi and has redundancy. )
These DVDs appear to have been burnt correctly and other vids on the Disc sound OK . . . but I'm wondering . . . .
