And there's absolutely no DRM on OTA digital broadcasts. The industry tried to add some by asking the FCC to mandate a "broadcast flag", but that went nowhere. OTA signals are DRM-free - some *may* have the flag in a vain hope that the receiving hardware will respect it, but no currently-produced receiving hardware that I know of does. And I doubt any of the stations bother even inserting the flag anymore.
Is this really true? I've been reading the AVR Forums for the last few months and apparently there are a lot of situations where the Broadcast Flag is being set. You wouldn't think that this is a problem, except that a lot of the DVD recorders on the market today do honor the flag and will only record programs that have it set onto DVD-RAM media (since that's the only media which supports recordable content rights managment). This has caused a lot of DVD recorder owners heartburn when they try to use DVD+/-R/W media and the recorders refuse to write to it when they spot the broadcast flag set.
In fact one of the most annoying situations is when the main program _doesn't_ have the flag set, but one of the commercials _does_. Then the recorders will bail out partway through the session when they see the flag set on the commercial.
