Sorry to correct you Geekster, but the problem you are refering to is not being caused by ac3enc, but by the byte size of the ac3. A few brands such as Pioneer cannot handle Intel (Little Endian) byte order, resulting in freezing. They need Motorola (Big Endian) byte order, which is now an option on Besweet on the ac3 tab. I have a Pioneer player and discovered this the hard way. So if you cannot afford an ac3 encoder, Besweet is perfectly capable of doing the job. Clown Shoes

Clown Shoes, I very much appreciate another explanation as to why I am having so much difficulty playing Besweet-encoded AC3 files on my Pioneer standalone DVD player. I guess I should have done more research rather than accepting the few criticism posts I read which did not go into detail as to "why" and "what" the problem truly is, and simply blamed the ac3enc. I believe that Besweet is a great program, and I fully support open source and freeware efforts. It's important to learn about a potential pitfall for DVD compatibility when encoding AC3 files. I will verify your assertion, but for now I stand corrected. Thank you so much for the information about AC3 byte ordering! :) Update (3-19-2004): Well, I tried re-encoding the AC3 files with ac3enc from the original .wav files, making sure to use Big-Endian (Motorola) / DVD byte ordering, and still no luck... The authored DVD still locks up when starting to play the AC3 audio created by ac3enc. AC3 files created from the same .wav files using Scenarist's built-in AC3 encoder worked fine, however, and the DVD played without stuttering or locking. Strangely, the AC3 files created by ac3enc had a noticable "click" in them which occurs at the same time as the DVD player lockup during playback (about 1.5 seconds into the clip). The "click" is not present in the Scenarist-created AC3 files. Maybe this is a dynamic range / overflow issue in ac3enc which affects playback compatibility on Pioneer units? I have not tried to play my discs on other models so I don't know. I can send you sample audio files if you wish to verify this effect. Maybe there's something strange in my .wav file contents? I plan to send audio sample to the authors so they can investigate this further.
