I used OGMRip to rip part 1 and part 2 of the Fellowship Of The Ring, 
extended version.  I used identical parameters for the rip and encode.  
Both files are matroska x.264/AC3.

File 1: 
File 'FELLOWSHIP_EXT_D1.mkv': container: Matroska
Track ID 1: video (V_MPEG4/ISO/AVC)
Track ID 2: audio (A_AC3)

File 2:
File 'FELLOWSHIP_EXT_D2.mkv': container: Matroska
Track ID 1: video (V_MPEG4/ISO/AVC)
Track ID 2: audio (A_AC3)

Both play fine.

However, the command:

mkvmerge -o "Fellowship Of The Ring" FELLOWSHIP_EXT_D1.mkv 
+FELLOWSHIP_EXT_D2.mkv

Results in the following error:

mkvmerge v2.0.2 ('You're My Flame') built on May  3 2008 18:59:12

No append mapping was given for the file no. 1 ('FELLOWSHIP_EXT_D2.mkv'). 
A default mapping of 1:1:0:1,1:2:0:2 will be used instead. Please keep 
that in mind if mkvmerge aborts complaining about invalid '--append-to' 
options.

Error: The track number 1 from the file 'FELLOWSHIP_EXT_D2.mkv' cannot be 
appended to the track number 1 from the file 'FELLOWSHIP_EXT_D1.mkv' 
because the track parameters do not match.

Is there any way I can determine which parameters do not match?

I am using Ubuntu 8.10 64 Bit

Thanks.  I could not find an answer in the FAQ.
