The Dig crashes during video playback (problem solved)

LagAdder · Post by **LagAdder** » Sun Mar 23, 2008 12:50 pm

As an example: The intro video crashes as the shuttle approaches the meteor. With the following error message:

"Error: (10x1A46): Unknown Chunk found at 2a93542: 0, 0"

Similar errors appear in automated sequences and the videos in the game. The problem is 100% reproducable and occurs on my PC as well as my laptop.

I googled a bit and the only information that was remotely related to my problem was, that some later lucasarts games do have problems whilst scrolling horizontally (that was on some handheld platforms).

Any idea that could turn me into the right direction to fix this problem would be very welcome.

sounds like a corrupted datafile to me, have you tried recopying the files and checked your disc for scratches?

What version of ScummVM? Using compressed data files, or straight from CD?

The problem has occured ever since I first became aware of ScummVM and has remained throughout all the versions I tried over the years, including the most current version.

The CD-rom is in good condition without scratches or dirt. Recopying the files did not solve the problem, as well as playing directly from CD.

Edit: The files are uncompressed copied straight to the harddrive.

The intro movie, unless I'm mistaken, is the sq1.san file. Mine (from the English DOS or Windows versions) is 50,124,786 bytes and has the MD5 sum "aeffce448ef3193110dab71d7cc27c15".

If I look at the part of the file indicated by the error message in a hex editor, I see

Code: Select all

2a93540&#58; 79db 4652 4d45 0000 461a 464f 424a 0000  y.FRME..F.FOBJ..
2a93550&#58; 2f04 2500 0000 0000 4001 c800 0000 0000  /.%.....@.......

I beleive the letters FRME indicates the start of the new frame. For whatever reason, your file seems to have zeroes there, or at least something that ScummVM can't recognize.

A damaged data file still seems like the most likely cause to me.

Got it fixed now. Some of the video files were indeed partially corrupted, as the md5sums didn't match those on the CD.

It must be some hardware issue on my desktop PC (probably the harddrive I copied to).

I copied the files at a friends computer and shoved them over to my laptop via network and now everything works fine (tested the game for the last two hours on the current version of ScummVM).

Thanks for turning me into the right direction! : )
