I have searched and found a bunch of old threads linked from the FAQ (one thread seems deleted, but still in the FAQ list). None seems more recent than January, 2009.
Is it still not possible to add an external HDD to the Motorola STBs? Are there perhaps models with more storage?
We have only a few hours of HD programming on ours and are finding that programs are being deleted faster than we can watch them.
Coming from DirecTV with boxes that can add external HDDs (and 80+ hours internally) this is a serious (one more on my growing list) disappointment with the whole FIOS bundle.
