Whats the best cheapest TV Tuner for Ubuntu?

Question

My family are switching from cable to having a HTPC. Im going to buy them a Zotac ITX computer with a 520m in it. I have found this cheap tv tuner that I have read works with Linux: http://www.ebay.co.uk/itm/DISGO-FREEVIEW-DIGITAL-TV-TUNER-USB-DONGLE-STICK-RECEIVER-DVB-DVB-T-/250949179221?pt=UK_Computing_Video_Capture_TV_Tuner_Cards&hash=item3a6dbc9755#ht_1454wt_1134

Will this record on one channel while I record on another? Is MythTV any good? If you have any other good suggestions for a tv stick (It has to be USB as the machine im buying wont have any PCI ports) for under £30 then that would be great! Sorry if this seems a clone question but it is different to all of the others that sound the same.

We will be using this HTPC for some 1080p Youtube videos.

Specs:

2GB DDR3 Ram
Nvidia 520m
500Gb HDD(Big enough for us)
Dual core 2.00 64bit Atom

Answer 1

Any DVB-T tuner will do, as long as you investigate the Linux compatibility before buying. Look into experiences from other Linux users with this device on forums, check the LinuxTV Wiki for details on the current state of support in the Linux kernel of a wide range of recording devices.

Don't bother for MythTV: it is outdated and bug-ridden. I can highly recommend using Tvheadend, a high-quality and versatile solution meant for recording and watching tv.

Use XBMC-PVR as a front-end to this all. You will get all the usual good that XBMC offers, plus a user-friendly, well-integrated live tv section that you connect with Tvheadend.
