Hi

If I covert an xvid back out to DVD format and select auto run with no menus in VSO ConvertXtoDVD and then try to play the movie in VLC I get this message, Assertion failed!
Program: C:\Program Files\VideoLAN\VLC\vlc.exe
File: vm.c
Line 1641

Expression: pgcit !=NULL

For information on how your program can cause an assertion failure, see the Visual C++documentation on asserts

(Press retry to debug the application - JIT must be enabled)

If I go retry VLC Crashes, But I can play the video in PowerDVD with no problems.
I have checked this problem on other computers from friends and family they all have the same problem.

Can Anyone Help Me
Thank You For Your Time.

To convert MPEG 4 to MPEG 2 the command fps=<framerate> will be required.

OK so how do I do that Please.

By looking at the frame rate of the source in Stream and Media info and adding the command to the command line manually, after the selection of all your options in the stream output menu. The command can be entered at the end of the video options, just add a comma between the commands.

Is the info you suggested In VSO or VLC I am still new at this.

The command is for transcoding in VLC. The VSO program may not be making a compatible file and I have not experience with this program.

Hi I have the same problem as the other guys (playing from the directory of a VSO created dvd ) this has only just happened on a particular dvd. I have tried following the previous post on how to rectify this but am lost. Can you tell me an idiots guide set by set on how to do this? All help would be appreciated.

The other guy (eagle777) said that the source was XviD (which is a MPEG 4 format) and he wanted to convert to MPEG 2. I suggested a way to do that in VLC as I am unfamiliar with the other program.

MPEG Conversion does not explain this. Both are MPEG2 and the same file just read in then written out. The programs that seem to be getting these results are DVD stripper types, I think. This is also only appearing, in my case, when directory playing is requested, ie DVD structure. It does not happen when a specific file is read.

FAILING: VLC message reporting:

A/R/I

STATEMENT:
The succeeding snip below is the original and plays. The failing
one is an exported DVD using DVDRemake Pro 3.6.1. Other players handle it correctly.

QUESTION: is it failing due to a "libdvdnav" return, if so what version is being used?

There is a known bug with DVD navigation that causes these issues (also some menus cause this). Hopefully someone fixes this.
