Most digital TV tuners work under Linux, but it’s safest and easiest to stick with a known, good model. I picked up my Leadtek DTV1000T card for about $80. It uses the Conexant CX2388 chipset, which uses the cx88_dvb driver module, but I didn’t even need to know that: Ubuntu, like all good distributions, found the card at boot and inserted the proper module automatically. If you use an unknown card with a similar chipset, you should be able to get it working, but you may have to load the driver manually.
