More and more people are running into problems where their recordings just STOP for no apparent reason. The cause could be Copy-Once (CO) copy protection, or CO-like behavior, IN COMMERCIALS!
JVC engineering has acknowledged that the CO-protection, or CO-like behavior, is in commercials but they don't know why... yet.
This has been occurring since at least Sep 2008 on all different makes and models of recorders, some old and some new, and all kinds of commercials from auto mfgrs to pizza. Some say it might be in movie trailers with fast-action flashes, etc. The CO-protection can be in one or several of the commercials, but you'll be able to find the FIRST one cuz that's where recording will stop, either at that commercial, movie trailer, etc. or immediately after.
Programs that are CO-protected in their entirety or in elements like the commercials will record OK to only these media:
- -RAM discs (a native VR-mode disc).
- -R/-RW discs formatted for VR-mode.
Once on those media, they CAN'T be copied to a std Video-mode disc like the -R/-RW/+R/+RW we use everyday. They can only be copied to another HDD or VR-mode disc, which are not universally playable like our std Video-mode discs.
If you record a program to a HDD and find that it shows a CO-protection symbol on the title, you won't be able to copy/dub that title to a std disc. However, you CAN delete the commercials... or at least the CO-protected one(s)... then copy/dub it to a std disc.
