Consider source as XDVD format MPEG file?

[headless chicken]

I have two films in MPEG-1 format ripped from VCD that I'm trying to put on a single DVD. TMPGEnc Authoring Works has the option to "consider source as XDVD format MPEG file" automatically checked. Should I keep this option checked or unchecked in this instance, and what are the pros and cons of both?

XDVD is a non-standard DVD format. It could mean that it's going to keep your audio at 44.1 KHz from VCD. It could mean that something is not right for DVD in terms of MPEG-1. There are restrictions on resolution and bitrate for DVD if you use MPEG-1 so maybe your input file violates those restrictions. The downside would be that a DVD player might not play a DVD created this way, but many players probably will not care. Just know that technically XDVD is not a DVD, so if a standalone player refuses to play it because it's non-standard, you can't complain because TMPGenc warned you.

Since VCD's video specs are actually fully DVD compliant, you only have to change the audio stream to comply. As jman says, the sampling rate needs to be 48kHz, not VCD's 44.1kHz. Other than that, you'll be good to go. So do this (as just one example of a workflow):

1) Demux the VCD MPEG1 stream (using, e.g., TMPGEnc's tools).
2) Resample the audio to 48kHz (e.g., using Audacity; there are many, many audio tools that will do this)
3) Mux the new audio with the original video stream (e.g., with TMPGEnc's MPEG tools again); this step may not be necessary (or desired) if your authoring tool wants to be fed elementary streams.
4) Feed the muxed stream to your DVD authoring tool. There's no need for it to be treated as "XDVD" as it is now fully compliant.

Just let tmpgenc authoring works change the audio to 224kbps ac3,no need to demux.

Thanks for the info, everyone. Although the input audio registers at 44.1kHz, I do believe TMPGEnc Authoring Works has an auto-resampling feature that makes it DVD compliant. My output indicates it's 48kHz which is a pretty convenient feature.

I suppose unticking consider source as XDVD format MPEG file won't have any major affect either way?

I would suggest unticking it in the hopes that it will fix whatever it is complaining about. But having never used this product and operating only on your statement that you have ripped from VCD, it shouldn't be giving you such a message. As tomlee59 pointed out, VCD video is valid without changes for DVD, it's only the audio that has to be changed. Having invalid audio should not per se flag some sort of XDVD warning, but again, I have never used this tool so I don't know. Maybe the audio is all it's complaining about. If you made some sort of change to the VCD video prior to sending it to TMPGenc Authoring Works, that might be what it's complaining about.

Anyway, try unticking as the option most likely to produce good results.

Keep it unchecked,only reason to keep it unchecked is if the dvd is non-compliant and no need to use any other program since tmpgenc will do it for you.

Ooopss sorry about the links. All inappropriate links have been scrapped from the allaboutvideo.weebly.com site. Just trying to offer my knowledge, thats all.
Feel free to comment on the tutorial. Good luck on xDVD conversion!
