I've always used skip ahead (set to 30 secs) to jump over commercials etc. Since "upgrading" to Quantum, the skip ahead button does not always work. I've narrowed the problem down to when the show you're watching is still airing (i.e. not done recording). The skip ahead function seems to work for a while until you reach a certain point in the program, then instead of skipping ahead, it jumps back to some earlier spot in the program. When this problem occurs, this earlier spot is always the same spot. To get around this bug you have to remember not to use the skip ahead button (easier said than done) or you're forced to fast forward back to the spot you left off. So once the problem starts you have to use the Fast Forward button to skip ahead.
Is this a known issue? Is a fix in the works? Very frustrating indeed.
Other gripes I have are covered in other posts...such as the laggy remote controls.
Thanks
