this morning. Haven't posted here in awhile nor introduced meself. Have been dubbing/recording for about a year now with my dvd/vcr player/recordersand need some help? How do i get rid of the blue/red scrambled lines that appear on the blank vhs tape after the recording is finished? I am using both 6 and 8 hour black vhs tapes. I am recording off of the dvr receiver. Plus, the sound quality on the blank vhs tapes are poor. I use a variety of name brands of vhs tapes for recording.

The mess on the tape after a recording, especially if you were recording over something else or trying to "insert", is the result of your VCR not having something called a "flying erase head". VCRs erase before they record, and the erase head is normally some distance away from the record head, so when you stop recording there's a varying amount of tape after that that's erased, garbled or mostly erased. With a "flying erase head" the erase head is part of the main drum and only what is being recorded over is erased.

These were present mostly on high-end and/or editing models. Since VCRs are all but dead, I'm not sure that any current models actually have that feature.
