I agree with you that it must be a TV issue as I have used Hard Drives on my computer with more than 300 items.
The TV can record live TV programs through an antenna, I don't have cable.
By locked I mean locked. When I first connected the HD the TV wanted to do a format before it would record. And in doing so the HD is now locked to that TV only and will record and play back. But when I try to use it elsewhere the other TV's do not recognise it when its plugged in. I have a PC and a Mac and both cannot recognise it due to a probable LG format.
that sucks LG isn't acknowledging the problem. probably got a low-wage generic tech support person that just types in your question to a database and reads or copy/pastes back whatever generic answer is returned.
same way we did things at Intuit. we actually risked being reprimanded by going outside of the generic answer database with clients on the phone, even if we solved their issue.
all i would say is to maybe use this one for only larger/longer videos and buy another smaller HD to hold another 300 smaller shows/videos.
seems they should have warned you in the initial setup that there was a # limit.
