Top Tip
- Crazy as it may sound, if you find that video and audio sometimes freeze (and there are no error messages in /var/log/messages), your aerial signal may be too weak. A signal booster made a significant difference in my setup (Hauppauge Nova-T (Conexant) + Avermedia 771 DVB-T, 2.6.13-rc7 + dvb kernel patches from CVS)
