I have 2 TiVos, both with identical hacks (Endpad,TivoWeb, dail mail, autospace, cron). One works fine, no glitches. The other glitches at infrequent intervals when watching recorded programs. The glitch takes the form of the playback skipping a second or so of video and sound. Usually enough to miss one or two words of dialogue. If I press replay it replays the section that glitched WITHOUT A GLITCH. Sometimes the glitches are a few minutes apart, sometimes an hour goes by without a glitch. Very occasionally (weeks apart) this TiVo will reboot. The disks were upgraded in March 2001, so nearly 4.5 years of continuous use. 1. Does this sound like an impending disk failure ? 2. What should I look for in and in which log files that might help ? All suggestions appreciated.
