I get excellent quality from Analog Cable or Boradcast TV captures on my ReplayTV using the KVCD3 template with the following tweaks:
Change resolution to 480 x 480 (352 was not detailed enough but 528 was overkill)
Change minimum bit rate from 300 to 0. (Also, eliminate the padding!)
Change 23.97 to 29.97
Use this Avisynth script:
Mpeg2Source("xxxx.d2v")
LegalClip()
FieldDeinterlace()
Cnr2()
GripCrop(480, 480, overscan=2, source_anamorphic=false)
GripSize(resizer="BicubicResize")
STMedianFilter(8, 32, 0, 0, 8, 32)
PixieDust()
BlockBuster(method="noise", detail_max=7, variance=0.5, seed=1)
GripBorders()
LegalClip()
This seems to work great for any type of capture. (If you are doing a movie you will want to add in IVTC to compensate for the original 23.97).
I use TMPGEnc and the current KVCD3 template with the tweaks above. The file sizes are small and I am still surprised by the quality.
The only negative is the encode times can be high. I am running around 3x real time time on an Athlon 2200+. (Most of the speed hit is PixieDust),
