I just replaced my 7 year old JVC with a new model and chose the Panasonic PV-8554-K. Is has a feature called Commercial Advance. It is supposed to fast forward through commercials when playing tapes you record on it. My God, It Works! I thought it would be some fancy feature that was too difficult to use or too wonky to count on. Nope! It's wonderful! I wish I had this a few years ago - Now I have 180 Seinfeld episodes to retape!
For those that are interested. It tapes an entire show you program it for, then it rewinds to the beginning of that session only, takes about 4-5 minutes and marks commercials and then stops at the end of that recording, ready for the next recording.
When playing back the tape it senses the commercial break - goes into fast forward until the end of the commercial and begins play again when the program comes back. Marvelous!
My wife says she knows she is in trouble when my VCR is smarter than she is. :-)
I am sure there are a lot of people out there that knew this technology existed. I can tell you it is worth it. But I would not want to marry one. :-)
