Hello, I've tried getting help from a few people who I know do capture card recording / speedruns / etc and none of them have been able to diagnose my situation so I'm hoping any of the fine folks here can lend a hand. I'll try to give you any pertinent information but just ask if you need more.
I'm trying to record PS1 gameplay, not only for speedruns, but just for any kind of gameplay. I've successfully recorded my SNES, N64 and PS2, but I'm having difficulty with the PS1. Here's a picture of normal footage

and here's what I encounter around 75% of the time

As you can see, it looks like the lines are getting split in a very weird way. The odd thing is that this seems to go in an out in between rounds, not recordings; that is, I can be playing a song, and either finish it or restart, and then play another song and, without having stopped the recording, the picture I'm getting has changed from one to the other. It never looks like this on my TV, by the way (I'm playing on a CRT). These are pictures from an interlaced recording; I have not deinterlaced this in any way, live or using AviSynth. Here's some information about my setup.
Capture card: Diamond VC500
Input: S-Video
Recording software: VirtualDub 1.9.7 or AmarecTV 2.31 with lagarith codec, both at 29.646431280978 FPS
Splitter: CE LABS AV 400SV distribution amplifier
Operating system: Windows 7 Professional 64-bit
Graphics card: GeForce GTX 950
RAM: 8GB (forget what speed, plenty though)
Hard drive writing to: 2TB 7200 RPM and otherwise good specs drive, F: path (not system drive). almost 600GB left
Again, I don't have this problem for any other consoles that I've tried. What could be causing this? It's a total crapshoot as to whether my video will look good or look terrible, and if I'm speedrunning, it's just about guaranteed I'll get both types of picture since it tends to change (seemingly between loading screens?).
I've constantly messed with the wires to make sure they're all snug and stuff like that. I really can't figure this out :/ I hope someone here can help me.
EDIT: Also, when I record with the 29.646431280978 FPS (PSX framerate, like using 30.0494069487205 for SNES) in AmarecTV, I get hundreds of dropped frames. The video appears smooth, but it reports frames that I guess are getting... removed? I don't know if this is normal or not. VirtualDub had a timing section where you could set something to correct any odd behavior when using unorthodox framerates, but I see no such thing for AmarecTV.
