MPGs formatted for VCD on PS3

So I have a pretty massive music video collection I've been collecting forever in every codec imaginable. The oldest discs I have date from 1999-2002 and they were a series of VCDs I burned. I tossed my entire collection on an external drive a couple years ago for easy access/streaming/organization. When I was streaming them through my old blu-ray player with serviio I had no problem playing most everything, including dozens of mpgs I just dragged-and-dropped off of those old VCDs and simply changed their extensions from .DAT to .MPG. Now it seems that since I've switched to the PS3 absolutely everything plays except these old .DAT files I renamed to .MPG. I've had to hunt down an ancient copy of VCD2MPG in order to run the problem files through. Its getting very tiring though and I would hope there's an easy fix to this either with a transcoding profile or something simpler I'm just missing, but I can't seem to figure it out. Considering these are basically the same files with some tiny bits changed at the beginning of the file I can't figure why the PS3 can't figure out what they are, but I can't imagine VCD compatibility was really important in the design specs of this thing.

Could you provide information about that *.dat file format (ffmpeg -i ) ? see signature links
Thanks

Delivering it in its native format causes a "The data is corrupted" error.

Yowza. OK, since upgrading to 1.4 all of the MPGs that were once SVCDs won't play as well, in addition to the previous problem with the VCD files renamed to .mpg. Again, same problem, .dat files just renamed to .mpg that used to play in every program imaginable but now the PS3 won't accept them and reports the data as being corrupted. These are mpeg-2 streams as opposed to the mpeg-1 streams the VCD were. This didn't used to be the case,and I can't recall if I just gave up and set all mpeg streams to transcode, but now they uniformly won't stream. Howsabout I just transcode all MPGs from now on? Seems like a silly solution though, but one I don't have a problem with.

Nevermind, y'all. I'm just gonna remux whatever doesn't work with VCDGear. I understand this is an obscure silly problem to have in 2013. However if anyone has an incredible idea, feel free to chime in.
