Very Lost with extracting mpeg from iso

[techmaster-1]

i have 2 iso images and i am using iso buster to remove the 2 different mpeg files and i seem to not have a problem with that but when i go to open either of the files in virtualdub it says "No Video Frames Found In MPEG File" does anyonre have any ideas what i am doing wrong i have followed the guides and according to them i am doing everything right, but this keeps happening. the whole purpose behind doing this is to merge the 2 mpeg files together.

The regular version doesn't seem to open MPEG2 files. There are some versions around that do. This one for example:

so then with this would i still go about everything the same way as far as opening the file. choose the divx 4 codec and then save as avi and then the same ofr the second one and then join them together????

I thought you could use File -> Open Video File, followed by File -> Append... But that only seems to work with AVI files.

For best quality you should open one of your MPEG files then save as AVI with no compression (or with a lossles codec like Huffyuv) fpr both audio and video. Then do the same for the second MPEG file. Finally Open the first AVI file with Open Video File, the append the second one with Append AVI Segment. Finally, save as AVI with the Xvid codec. You'll need lots of free disk space for the uncompressed intermediate files -- about 30 GB/hour with Huffyuv encoding, twice that for uncompressed.

You'll probably also have to make sure the two uncompressed AVI files have the same frame size, frame rate, and audio sample frequency. It sounds like you have two parts of a larger video so you'll probably be OK.

You can save yourself some time(and disk space) and encode both of the mpegs to XviD seperately. As long as you use the exact same audio and video bitrates you can join them afterwards.

He can also join the two MPEG files using the command line COPY function (again, the two source files have to be the same format):

copy /b input1.mpg + input2.mpg output.mpg

Then convert to XVID with VirtualDub or some other program.
