It can be done, and not so difficult. All you have to do is resize your video to 354x480 and use a really stingy bitrate like 2000 mbps (which is a minimum) and use a single-layer disc. Only problem: it will look like a nightmare of visual crap.
Is this 6 hours of continuous video that can't be edited into two or more smaller clips? Even at lower MPEG2 bitrates, you can't fit 6 hours of full-sized video even on a double-layer disc at decent bitrates. The formula is low bitrates = low quality, and it's true for DVD as well as for BluRay. And bitrate needs differ for different kinds of video: if you have lots of action you require full-sized frames and higher bitrates than for static video like melodramas.

VirtualDub color corrects and applies other VDub filters in RGB, which takes more storage space than YUY2. I assume that you did capture in YUY2 and not in RGB -- for several reasons, the latter is never recommended for capture. To save about 30% storage space over RGB, you could save your VDub output as YUY2 and use the lossless Lagarith compressor which will save another 5% or so over
Huffyuv. You can get Lagarith and its handy-dandy installer at
https://lags.leetcode.net/codec.html. And consider this: since your MPEG encode for DVD will be in YV12 color, you can use Lagarith to save your VDub final output working files as YV12 and save an even bigger chuck of file size (and VDub will probably save it doing a slightly cleaner job than some encoders).
But how could we possibly advise about filters and colors if we don't know what your videos look like? Anyway, it's highly unlikely that all 6 hours of that video could use the same filters and settings from start to finish. Most people cut long videos into smaller workable segments and suit the filters for those particular problems. Since you're resampling your audio, you'll need to start with the big original capture joined to to your clean new video, then start cutting away after that.

We don't need 5 minutes of video to advise about problems. And as stated above, very likely you will have mighty different kinds of problems over 6 hours of video. About 8 to 10 seconds of YUY2 unfiltered original capture with some form of motion will suffice. If you have different problems on different video segments, make several small segments for uploading. Also note that if your samples are in RGB, your samples will have to be far shorter than 10 seconds and we can't check for proper legal YUV capture levels after they're been resampled to RGB.
