missing channels on DVB-T scan

[garymeds]

can't seem to pick up many channels on ny HVR-1300 - usb nova-t stick shows much more from the same aerial amp/splitter.

the hauppauge scanner picks them up (below) as does windows media center. if i enter 801834kHz in a manual scan, the config app stops responding for awhile and goes nowhere..

attached config.log - appreciate help..

Do a scan, then post the config.exe.log and config.exe-native.log and I'll see if anything stands out.

here we go - thanks sub..

Try enabling the 'explicitly scan DVB-T Offset frequencies' setting on the Misc tab.

[garymeds]

that's cracked it! thanks sub!

Offsets are only used in the UK and Australia. Most devices auto detect and use the offsets, but there are few devices that dont.

well, i thought it had workd as could map channels but got 0 length recordings and can't watch live tv via this card (i have 3 tuners so only just noticed it can't get a signal). seems to pic up 60% of channels but can't use them - is like no signal.

strange though, as windows media center can pick up all the channels from that card.

have done a scan as above and attached (removed bda cache files first) - this only seems to affect the hvr-1300, nova-t stick is fine.

many thanks!

erm, anyone?

There isnt any obvious problem in your logs. All I can really suggest is checking that its using the frequencies you expect in your area. If its not, and its picking up weaker signals from near-by areas, then we'll have to work out why, or make sure your selected .ini scanning file has the correct frequencies.
