Many thanks for your helpful suggestions. In the end it appears to have been an aerial problem. With the Hauppauge winTV novaT stick I tried an old internal telly aerial and was able to scan channels and watch TV using Kaffeine. It also seems to be particular about the usb interface on the host. For example with identical kernel configuration I was able to get good reception on an athlon-cpu box with an nvidia chipset and nothing on a intel-celeton-cpu box with an ati radeon chipset. Overall the avermedia device gives better performance (than the hauppauge device) on the Linux setups (all BLFS) I have tried over the last year. For the avermedia device, it is easier to be recognised and channels easier to scan and picture quality better. Thanks again for your help. yours sincerely Lux-integ -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
