Well, personally I consider anything worth saving to be worth capturing to huffyuv lossless or MJPEG near-lossless and then deinterlacing and converting to MPEG-4 @ 2700kbps for an archival copy that looks as good as or better than (thanks to the right Avisynth filters) the original. For me, "anything worth saving" includes all the TV series I like which are unlikely to ever be released on DVD (mostly short-run but interesting shows cancelled early on, and cable/foreign shows with relatively small audiences), and shelves full of old movies on VHS, Betamax, and laserdisc that are unlikely to ever have DVD or HD-DVD/Blu-ray releases, or whose DVD release is lower-quality or censored.
For me, collecting such "orphaned" films and TV shows has become a big hobby. Everything from extended versions of big-name films, to promising TV shows cancelled after 4 episodes, to made-for-TV movies, to "classic" adult films from the 70's and 80's that were censored in the PC 90's, has been archived in my collection. I just love digitizing anything entertaining that's unlikely to hit DVD.
Capturing lossless or near-lossless is important to give Avisynth filters and deinterlacers a clean unrecompressed signal to work with--even at high bitrates, single-pass MPEG-2 is going to introduce its own layer of artifacts, and even artifacts not offensive to the eye can make some Avisynth filters work sub-optimally. A final output format of XviD MPEG-4 at 2700kbps provides quality visually indistinguishable from the original for 24fps and 30fps sources once filtering and deinterlacing are done, though for very rare high-quality video sources I rarely deinterlace to 60fps to preserve the extra field information and up the bitrate to 4000kbps. I've only done 60fps for a couple of very special, irreplaceable sources; most can either be IVTC'd back to 24fps or I'm willing to lose small amounts of motion information and deinterlace to 30fps.
