Portable TVs of the 50s were intended to work on a built in antenna so they had decent sensitivity. Channels assignments were alternated so adjacent channel and intermod rejection were not the primary design objectives. IF traps were fewer or often omitted altogether. The design served the intended markets quite well. What you see on cable would be expected in current conditions.
The VCR is operating with no other channels so it will not suffer interference. You could try padding the cable signal by about 20 db, or whatever it takes to keep just above the threshold of snow. That will reduce intermod and likely adjacent channel interference as well.
