My 722k has been acting odd for the past week or two. At first it was just the occasional "slow guide" problem then it began having more and more slow to respond buttons other than the guide. I changed batteries in the remote first thing. Still had issues. I used the red reset button on the front panel and it seemed ok at first, but about a night or two later it seemed just as slow as before. The internal hard drive was not full (I have seen it slow to a crawl when it gets full) and had about 25 HD hrs available.
Now I have been noticing what appears to be dropped frames on some recorded DVR shows. A character will be talking and part of a word will just clip out and the image seems to jump a few frames. I am worried I might be about to have yet another hard drive fail and take a bunch of fall shows I have not watched yet with it!
All this leads to ask:
1. Any 722k updates came out recently that seemed unstable that could be the cause of my problems?
2. If I use an external USB drive for my recordings, do you see any sluggishness from using external USB vs internal drive?
