I recently took the plunge and installed Mythtv, building myself a PVR with 2 DVB-T tuners.
My backend setup consists of a AMD 5050e, with a GA-MA78GPM-UD2H motherboard and 4 gig of ram, running Fedora 11 and Mythtv 0.21.
I initially tested the waters with a single PCI tuner, which was a Twinhan DVB-T Mini-Ter (bt 878 based) card.
Over the weekend I also added a Leaktek Winfast DTV 1000S, to get this to work I had to install a version of linux dvb that is currently under test with specific support for the card.
All in all, I am very impressed particularly with the web based interface of mythweb and wonder why I put up with buggy windows dvb/pvr software for so long.
At present to play recordings, I have been downloading them to my Windows pc using Mythweb, and then playing the mpg file with Windows Media Player.
I have also tried playing the files across my home network via a samba share.
The problem I have is that I seem to be unable to seek in the recorded files, otherwise they do appear to play perfectly fine.
When I do try and drag the windows media player slider to advance the file, it snaps back to the current position where the file is playing.
Is there any way to fix this or a setting I can change?
I find that if I re-mux the recording with something like VideoRedo on my PC, I can then jump forward, backward or to anywhere in the file I like without issue.
Longer term I do plan to run a front end, but at the moment my loungeroom PC connected to my plasma runs Windows XP Pro and is used by my family for email, web, etc....
