people have that same problem with the spiderbox , I believe 8000 channels is the limit for a HITECH box , including radio channels as well as tv channels

the spiderbox 6000 only allows 6000 channels so its especially difficult with that particular box to stay under the limit

the old spiderbox 9000/7000/9900 were 10k worth of channels as a maximum

so it varies from box to box
