I have been using a Hauppauge 1800 in one machine and a Hauppauge 1250 in another. Both have QAM. The 1800 has a separate analog and digital tuner. The 1250 is a hybrid ( one tuner for all bandwidths). I have only been using them for playback purposes through kaffeine, and they worked well once I found the area I was in to scan. As far as setting up a dvr box, having tried it as yet. the prices have come way down, and you can get the 1250 for around $50.00 with remote.
