That's of no use whatsoever! I'll explain it again . . .
I know how to use fast forward
When I select the first fast forward speed it goes fast for a SHORT while, then it slows down to around normal speed, then it goes fast again, then it slows down - it keeps on doing that without me pressing any buttons
Okay sorry for that, I misunderstood. It's going to be down to the hard drive in that case.
I would first recommend performing a clear and delete but unfortunately it does mean clearing all the recordings from the hard drive. If you find there are no changes afterwards then what I'll do next is send a technician out so he can replace the box for you.
I have added the instructions on how to clear the hard drive here so please let me know how you get on.
Why is fast forward so poor - on the first setting it goes a mite faster for a few seconds, then reverts to normal speed, then fast forward a bit - repeat, repeat?
Can't wait for BT/Sky to get fibre to the cabinet - so I can got with a decent service, hardware and software
Totally agree. Very poor compared with the competition. Notice how fast forward is twice as slow as rewind. You have to jump past where you want to go and then rewind to get anywhere in a reasonable time. Just one of the many foibles you have to live with using Virgin Media Tivo.
The speeding up/slowing down has been reported many times over the years and is due to bitrates on certain channels. There are even videos on youtube. Surprised VM are blaming your hard drive. Just goes to show how we are ignored by VM. A quick search will result in other threads.
