You may have to. Go back and read the whole thread, and I think you'll be illuminated.
What are your ARSL's? I found that by tweaking the ones I had I was able to prevent my HR24-500 from getting the slow responses.
My example was: "AALL HDTV Rangers" in Sports -> Hockey
I changed it to "AALL Rangers" in Sports -> Hockey and my HR24 stopped having issues. It was explained that HDTV is an unnecessary keyword and could be causing problems - but the HR24 would automatically prefer HD over an SD recording airing at the same time.
It was also recommended to change mine to "AALL Rangers Events" in Sports -> Hockey which would only record the live games, thus skipping over Pre-Game and Post-Games. I didn't switch mine over yet (HR24 is in a bedroom now and I don't use it as often since getting the HR44) - but that is also an option.
Here are my ARSLs
on my HR24:
AALL PURDUE EVENTS NNOT WOMENS & Sports, Football
AALL INDIANA EVENTS NNOT COLTS INDIANAPOLIS & Sports, Football
ANDY GRIFFITH & Audio & Video, Black & White
on my HR21:
AALL PURDUE EVENTS NNOT WOMENS & Sports, Basketball
AALL INDIANA EVENTS NNOT WOMENS PACERS & Sports, Basketball
any thoughts on why these would lock up both our boxes regularly?
