Six months ago I upgraded the HD to 80MB. The upgrade went smoothly. The system has worked fine for the most part. Modem connects every day. Shows are recorded every day. I installed two fans so the box is now cool to the touch. The playback is always steady, no stutters. The only problem I have is with shows that I recorded that I have not watched for a week or two. Sometimes, when I am viewing one of these shows and I hit fast forward x1, x2, etc. the system stays in fast forward and ignores all further remote commands. If I hit the stop key 50+ times in a row I can usually get it to stop but once a show exhibits this behaviour I dare not use fast forward again or the show is likely to fast forward to the end of the show at which time the show will end and I can watch it from the start again as long as I do not use fast forward. Other shows more recently recorded will not do this even right after watching a show that has done it. Any ideas what is going on with my box and what if anything I can do about it? Thanks for your help.
