Stuttering video/sound from Presto PVR

  Jem 20:52 23 Jan 2008

This DVB device (a USB dongle) + Newsoft PVR 5 software works well with some freeview digital channels but on others the picture and sound are jerky.

The aerial signal is good and I have visited the NewSoft site and installed a 2005 Microsoft patch for XP SP2. This didn't cure it.

Has anyone got any ideas?

All channels vary in transmission quality The signal is not only dependent on strength but also quality Do you have both indicators

Yes. Both appear reasonable.

I think however that I've discovered the cause. My wireless router is close to the PVR device and if I switch it off the affected channels start working just as well. If I then re-connect the router, the channels keep working. But if I close down the PVR software and re-start it the problem recurs.

Looks like some kind of radio frequency interference which might explain why it only affects some channels.
