Post Encoding problems in low motion areas

I'm trying to encode the Opening to "Love Hina" and have run into a few problems:

My main issue is the title. The video leading into the title and the displaying of the title all have very little motion going on onscreen so when I encode it (even in high motion using mutli-pass settings) it freezes the image and doesn't take another keyframe until the title has passed. End result is the title is never displayed! I've re-encoded it sever tiles with several differen't settings with no change in this problem

Next I'm having issues with minor freezing in points of high motion. There is a lot of zooming and panning in the opening and in many of these areas it will hic-up during high motion. I encoding at 1,000kbps and have a file size of about 10 megs. I'd like to keep it under 15megs if I can. I'm also open to using differen't codecs such as MPEG or what have you.

My source is the R-1 DVD (NTSC) ripped with SmartRipper 2.41.
I'm encoding it with FlasKMPEG version 7.8.39 and trying DivX 5.0.3 for video and the Divx audio compressor at 160kbps/48kHz for sound.
I'm encoding at 1,000kbps with a video res. of 512x348 and the deinterlace option enabled. I'm using the Mutlipass, nth Pass mode with High Motion setting in bitrate modulation (-0.25).

My system in a 1.125ghz Athlon with 160 megs of RAM (I know, too little) and a G-Force 1 card made by Creative using the latest Drivers and DX9.

Any suggestions would be great.

"512x348"
Use a more acceptable resolution of 512x384, that conforms to the 4:3 aspect ratio.

I have encoded the Love Hina opening before, though I was going for maximum quality at 50MB. My source is the same as yours. I did not encounter any problems with this particular opening, so I believe the problem lies with the procedure that you are using.

I recommend that you try the older and more reliable Flask versions. Or if you are feeling adventureous enough, use Avisynth and its accompanying Decomb filter, and compress in VirtualDub.

You mean like 320x240? Well being my first video I just used the highest video res I'd seen for such things, which was 512x348.

But in the end I messed around with my codecs a bit and DivX 4 High Motion for video and MP3 for the sound. I set the bitrate to 1500 and keyframes to 7 and it turned out perfect. No skips, pauses or anything and a file size of 13.6 megs }

That's quite alright. Typical of Megumi Hayashibara.

The theme songs used throughout the episodes are really nice and heart-warming pieces to listen as well.

i make 640x320 widescreen Ripz on my 533MHz 96MB Ram and theyr at 600k bitrate and the kwality is good enough for me. If i play them on hig hkwality tho they slow down, so i play on medium kwality nad it is good.
