I changed from a PVR 9300T to a new FVP 4000T- ITb in December.My first impressions were very mixed- really disappointing method of operation compared to the 9300T. Every action was clumsy and needs at least twice as many steps to execute. Just deleting a recording takes 4 actions for each recording date! The programme pictures are so unnecessary- a list of recordings is all that is needed. Why have we gone from simplicity to clunkiness? My second comment is more positive- delight at the ease of catchup on demand using wifi and the smooth operation.
Using on demand is fortunately good, because its now the only way I can reliably watch programmes. For the last 6 weeks or so my 4000T has stopped reliably recording. I usually get a warning message followed by pixellation and in addition the programmes are starting 3-5 mins late. I have a Sony Bravia TV and the aerial was fed to the PVR first and then to the TV. I'm using HDMI. I've now changed to a different (Samsung) set which has a different external aerial but this is no better, which makes me think its a PVR fault not a signal fault. The signal strength is 80% and the quality is shown as 100%.
If noone can help I shall return the PVR and go for a Panasonic instead.
