custom profiles in XviD 1.0.3

I've been using XviD for the last half year or so to reencode videos to run on a Casio E-125 I was given. (BataPlayer is the decoder if anyone needs to know.) Since a lot of files had begun showing up that didn't play on my old version of XviD I upgraded to 1.0.3 (nic's as of December 14th 2004). However, I found that all the controlls had changed and the one setting that I needed access to to squeeze the needed performance out of the PocketPC has been removed. I had been using nic's codec that I downloaded July 16th 2003. I found that by setting the "alt. curve max bitrate" to 2000 I could get decent framerates (~12fps) at 320x240. All other settings were still at the defaults. The problem is that in the new codec, this setting seems to be in the profiles. The DXN Handheld sets the bitrate much too low, but both the DXN Portable, and whichever AS profile that has the next higher bitrate are both too high. So, is there a way to make custom profiles? If there is no way and no plans to support a way, could someone explain the workings of installing codecs to me on a level that I could have the current codec installed for normal stuff, but also have the old codec installed for a few encode only jobs? This is espicially important for files can only be read by the new one, but must be encoded by the old one.

Best I can recall those values don't do anything in 1.0.3 anyway. You would need to use a 1.1.x build. Although I thought that Nic's build was a CVS head build anyway? Not 1.0.3? July 2003. That would be xvid.dll for VFW wouldn't it rather than xvidvfw.dll and xvidcore.dll? So you should be able to have both installed. Not sure about registry keys though. By the way, I can add a custom profile if you want it.

First, my bad. Since the codec doesn't have an about box, I have no idea what version it is. It's the one that's posted on his site right now. (just to make sure I have the right site) Second, "July 2003. That would be xvid.dll for VFW wouldn't it rather than xvidvfw.dll and xvidcore.dll? So you should be able to have both installed. Not sure about registry keys though." Do..wa..huh? My level of understanding of FourCCs is that in some magic way, Windows matches the FourCC value in the video with a dll that is used for decoding. Searching the system32 directory, I see that I have all three of the files you listed. Who knows which is used for what though. If someone felt like adding a way to make custom profiles that would be exactly what I need. However, if you mean you'd add a profile just for me, don't worry about it. That would be selfish on my part. It would only apply to my one personal use and may be subject to additional tweaking at any time. For now, I reinstalled the old codec on the computer I use for encoding. It'll do for now.
