Re: Strange Problem with AC3 File and TMPGenc DVD Athor

Hi all,

emmm... may I come back to an older reply by bitbrain2101?

On August 6, 2003, he asked about a problem with Digigrams MC en- / decoder. I do have exactly the same problems: AC3s produced by this program cannot be used in other apps like TMPGEng DVD Author and cannot be "reconverted" into 6 waves by BeSweet. On the other hand, the Digigram DEcoder cannot produce WAVs from AC3s made by e.g. the AC3Machine which uses the ac3enc.dll.

I have come over a strange problem encoding AC3-files with SoftEncode or Digigram Multichannel Encoder. I have encoded AC3 5.1 and 2CH Stereo files from mono wav-files with 48k/16bit.I can play and hear these files with PowerDVD and the Dolby Logo is shown in PowerDVD.But if I try to import these AC3-files in TMPGenc DVD Author it tells me "illegal File".If I import AC3-Files ripped from DVD everything is ok.I examined these files with GSpot,my self-encoded AC3-files are unknown,but the DVD-ripped AC3-files are shown as AC3-files with their bitrate.Is there perhaps some kind of header missing that my self-encoded files arenīt recognized ??

In the following reply (by "nuked") there was an remark about the "intel byte order" (vs. "motorola"?). I guess, this could be a reason, but...


...sorry, where ist the flag set? What do I have to change to make Digigram's en- / decoder work compatible???

Trying to fix the output file using BeSplit / BeSliced leads to an empty (0 kb) file. Log:

What does "error 59" mean, and how can it be fixed?

Thanks in anticipation!!
