    I used to do this successfully with Authoring Works, but the app crashes after I switched to 64-bit, even if I run it in XP in the Virtual Machine.

    I create a DVD with many VCD quality tracks. With Authoring Works I didn't have to do anything special, it just knew what to do.

    All my source files are already in VCD format. With AVStoDVD I set the disk resolution to VCD. I switch off all Auto modes. I set each track to QuEnc CBR, 1150kb/s. I set the audio to MP2, 224kb/s. I fix the aspect ration in AVISynth section. I switch on "Edit Command Parameters at runtime".

    With each track I change the script from -mpeg2mux to -mpeg1mux.

    If I use VLC to view the codecs for the created files they look the same as disks created with Authoring Works. VLC plays it flawlessly, as does Windows Media Player. If I burn the disk and play it with VLC it is still fine.

    In my standalone DVD player there is serious breakup at the start of each track, and then wobblies during the track.

    Is it something I am doing wrong, or is there a problem with QuEnc with these setiings?

    If it is any help, the script for QuEnc reads as follows:
    -i "G:\VIDEO\Temp\DVD_0_0609_1.avs" -o "G:\VIDEO\AVStoDVD\DVD_0_0609.m2v" -b 1150 -1 -hq -novbr -scene -trell -aspectratio 4:3 -nointerlaced -mpeg2mux noaudio -dc 8 -priority 5 -auto -close

    I change it to -mpeg1mux before letting it run.

    Should I change it to -nohq (not high-quality) and -notrell (no Trellis Quantisation)?

  2. Have you adjusted the audio frequency to 44.1 kHz?

    Please post the project log as well.

    VCD audio is 44.1 kHz and it must be changed to 48 kHz for DVD. I do not use AVStoDVD but I do not see in your post where you made this change. I think this is what _MrC_ is trying to tell you.

    VLC will play anything that is possible to play, whether it complies with DVD standards or not. A standalone DVD player might not play a DVD correctly if the audio is still 44.1 kHz.

    If you don't need menus, we had a post last week that muxman (it's free) can accept MPEG-1 VCD video input and produce a DVD from it. Just remember you must convert your audio to 48 kHz and muxman can't help you to do that.

  4. What I don't understand is if "All my source files are already in VCD format", why the video is being reencoded at all since it's already DVD compliant. Why degrade nasty-looking video even farther?

    Yep, right, I should always re-read post befor clicking "Submit Reply"...

    BTW AVStoDVD does adjust audio frequency to 48 kHz (SSRC(48000)), thus if macnab has not touched the AviSynth audio section, it should be OK. That's another good reason to have the AVStoDVD project log file.

    As MrC said, this is done automatically.

    The main point is to have it 352x288 already. The files are mostly sourced from VHS so the quality sucks from the start. The people just want their memories on disk.

    I do need menus.

    Tested by changing the script to -nohq and -notrellis and the problem is fixed. I think maybe QuEnc should ignore them when using MPEG1, but problem solved. Apart from the fact that I need to make 3 changes to the script for each track. But then AVStoDVD wasn't designed for my use of it.

    Thanks to all.
