Joining VCD (.DAT)

[BudgetKid]

I know this is not a new question, but i wanna know how do you join two .DAT files together? (~500 mb each)

My reason is that i want to play it on my PSP. (I know how to use 3GP)

Now i have already read the guide to convert VCD to DIVX http://www.doom9.org/index.html?/mpg/vcd2divx.htm . So i did, i followed everything it says. It worked just fine with a 5mb mpeg file!!

But the problem is when i wanted to open the main file i want (500mb) with VirtualDub, it has an error saying it's "damage or imcomplete"

(and yes, i used VCD Gear to convert .DAT files to MPEG...from there it says to use VirtualDub.... )

Now i didn't stop there. I downloaded VirtualDubMod...and it loads the MPEG file fine, but it only load the first 4-5 minutes of the video. (i think it's the first chapter)

So now im just starting over.... :(

I now have two .DAT files that i want to join.....any help, please????

NOT OVER!!! when i converted the VCD's to MPEG, i tired to join the two MPEG's together with TMPGEncDVD1.6 but my computer is way to weak to handle that. ...it has ANOTHER error!!!

1.Use ISOBuster to rip to HDD or convert.
2.Use TMPGEnc->MPEG Tools->Merge&Cut
