P.S: Does eac3to detect the problematic DVDs to have pulldown flags? If so, please try using the "-keepPulldown" switch. Maybe that helps getting rid of the issues? I suspect that maybe those DVDs have mixed video/film content which eac3to may fail to properly detect. If that is the case the "-keepPulldown" switch should fully solve the problem.

I can not drag'n'drop eac3to app. and hddvd/bd files to cmd window on Vista system on my laptop. Do you know how to fix it?

I've no idea. I don't think this is a problem I can fix in eac3to.

Error: "This audio conversion is not supported."

Why ? I just want to slowdown this AC3.

Works for me. Can you please post the full log text? Please don't type it. Please copy&paste it. Thanks.

I recently got one of the new geforce 8200 motherboards that can send multichannel LPCM over HDMI and have been trying to get it setup properly. I am currently running it in XP SP3. I was able to create a 6 channel FLAC file no problem using eac3, and it plays fine in MPC with madflac. However, for some reason my receiver thinks it is getting a 7.1 channel file, instead of a 5.1 channel file, and the surround right and left channels come out of the surround back right and surround back left channels (I have a 7.1 system), while the surround left and right speakers are silent. All the other speakers (including sub), seem to work fine, except for stuttering, which is most certainly a driver issue, since it happens for all audio tracks.

What I'm trying to figure out is whether this is a another driver issue (quite possibly), or an issue related to how eac3 encodes the tracks. Maybe it is encoding the side surrounds as the back surrounds? This seems unlikely and I can't seem to find any reason why eac3 would, but hopefully someone can chime in and shed some light on the situation.

Hmmmm... This may be a bug in madFlac or in the driver. Don't know for sure. It's definitely not a bug in eac3to. Can you please post a report in the madFlac thread?

In HD DVD there's a possibility the chapters to have or not names and in blu-ray not such thing. Anyway, when chapter names aren't available haali media splitter displays them like in the 1st screen. But when names are available, even if they are chapter 1, chapter 2, etc are displayed like in screen 2, which in my opinion is much prettier. So, what i want to ask is eac3to to add names (chapter 1, chapter 2, etc) when they aren't available from the source.

I generally don't like the idea of manipulating our precious muxes just to work around how a specific filter behaves. What happens if in 6 months there's a new filter (or a new version of Haali's filter) which works differently? Maybe that new filter shows "chapter xyz" by itself - and in the locale language of the OS? The muxes we create today would then not be able to make use of that. Instead we'd see the hardcoded english text.

Still if the majority of you guys prefer to have eac3to fill in a "dummy" chapter text, I can add that. So let me know your opinion. Also, would you prefer "chapter" to be written as "Chapter" or as "chapter"?

Thanks, will give that a try.

Just a friendly reminder that the bug still exists, in case anyone is interested. I will wait for a bugfix before I process this one.

Are you sure that you're using eac3to v2.46? Please check the log file to make sure. I don't understand why you should have this problem. It works for me with an external DTS-ES file at least. Don't have an EVO file ready with a DTS-ES track in it, though.

When the PCM file was demuxed, eac3to wasn't reading the file at all, so I had to force the options.

Edit: Another go at demuxing, resulted in a 48 kHz wav file.

Hmmmm... I've checked, I don't have a m2ts sample here with 96kHz PCM in it. Would you mind uploading a little sample for me? 20MB should do the trick. Thanks!
