I've got a PCMCIA tuner card which works fairly well on a good aerial but the sound is constantly out of sync with the picture.

Does anyone know of a fix? Is it the software or an inherent problem with this sort of card?

I am using Intervideo software that came with the card - is there a better one?

As it's a PC card I take it you're using it on a laptop - does it have a hardware sound / video card or software? It may be that it just can't sync properly because one is software and the other is hardware, and so runs more slowly as it can't actually keep up.

Hi Vince, It is an old Thinkpad with on board sound so maybe that's the problem. I would have thought that any software worth it's salt would have a latency setting to get around this but I can't find anything. The sound is about 0.5 seconds behind the picture

Maybe some better software is the answer?

Could try messing around with the hardware acceleration of the sound device.

I've seen 'syncing' issues with that before...

Some software does include an audio delay for fine tuning of 'lip sync' - xbox media centre for one...

Or it could even be the CPU isn't keeping up - what does TaskManager say?

Try recording it on your machine and playing back on another (better performance) machine ?

Might be worth a go - I've not had much experience of using tuner cards so I couldn't recommend any - I'd guess there are some forums which cover such things.....

Cheers

Turn off video h/w acceleration...(if it exists!)

If it is DTV then this is an indicator of poor signal quality NB signal quality isn't the same as signal strength.

Just found a copy of Intervideo DVR3 and it it much better than the generic prog that came with the card. Latency is still there but not half as bad now.

Particularly when capturing video have found that the format used - ie MPEG 2, 4 or AVI affects latency.
