When I play back some of my friends 8mm tapes 7 out of ten play perfectly and the other 3 have two interference horizontal lines (3/4" wide along the bottom third of the picture. The top 2/3s of the picture is locked in like a rock as is the rest of the picture and the horizontal interference. The sound is also mushy garbled. There is no tracking adjust that I can see on the Sony unit. The bad tapes capture just fine (with the interference lines) through firewire or analog through the ADVC-300. The Filters on the 300 do not change anything. Switching on DNR or TBR in the sony unit make no difference. Are these tapes bad or what?
