What is MythTV
Basically, is is a linux implementation of Media Centre, but goes much further
Ok, so it is not yet up & running, but here's the story so far...
Around mid 2007, I decided to build a HTPC. I spent a while googling for info on what sort of spec of PC was required, and I bought parts from suppliers like Quiet PC and Komplett.ie. I assembled all the parts, but the PC would not boot. Turned out to be a dud processor so I returned that & got a replacement. That took almost 5 weeks to get sorted out. When I got the replacement processor, I tried again to fire up the shiny new PC, but it would not work. After some unsuccessful fiddling, I put it all away for another day.
Then, around December 2007, I decided I needed to upgrade the graphics on my games PC, as it was quite a bit out of date and was getting a bit slow.
I started shopping for AGP graphics cards, and came across some cheap AGP cards with TV out. So, I had an inspriation, and instead of buying a high end AGP card for gaming, I bought a cheap AGP card for TV out and also a high-end PCIe card :)
Yes, you guessed it. I robbed all the new parts I had for a HTPC : Intel C2 Duo E6750, Abit IP35 motherboard, 2GB Kit of OCZ Platinum PC6400 DDR2 Ram, one of the two Samsung spinpoint 500GB HDDs, and I added the PCIe graphics card, to make my new games machine. Sorted. Happy Days. :)
Recently I decided I'd resurrect my HTPC project, and I assembled all the components from my old games machine.. 3.4Ghz P4EE, Abit IC7-G Motherboard, 1GB Ram, together with the Hauppauge HVR-3000 Tuner card, Samsung Spinpoint 500GB HDD, and the new quiet Akasa fans, and Scythe mini-ninja cpu cooler I had bought.
I had a bit of trouble reconfiguring the BIOS, as I had previously been using 2 Western Digital Raptor drives in RAID0 (striping), and had lost the manual for the motherboard, so that took a bit of trial & error to get the onboard IDE working together with the SATA HDDs.
I got that sorted, and decided I'd try a MythBuntu install, and see how I got on.
I did that, and got MythTV installed, but not much luck with my choice of Tuner Card. :(
It is still not working correctly, but I'm hoping the latest v4l-dvb with Steve Toth's DVB-S2 updates will sort that out.
Some links I found useful ...
After a lot of messing around, I finally managed to get my HVR-3000 up & running for DVB-S.
basically, what I did was as follows :
(I believe the MFE means multiple front-end, as the card is both DVB-T and DVB-S capable, but I'm only interested in DVB-S).
Now, you can scan for channels, and tune a specific channel using szap, and record it to an mpg as simply as:
cat /dev/dvb/adapter0/dvr0 >recordedvideo.mpg
You can then watch the recording using mplayer (after stopping the cat command above)
With MythTV, I had a problem after all my messing around with configurations, where the mythtv frontend would simply jump to a blank screen
and not even show the main menu.
In the end, after advice from the mythtv users mailing list, I removed the mythconverg database, which solved my problem.
The picture is still not 100%, but it is watchable. I believe this is simply down to a configuration of the mythTV frontend.
The next step on my list is to get the TV Guide working. The XMLTV included a grabber (tv_grab_uk_rt) which will fetch a tv guide from the Radio Times website, for the next 14 days, and provide this data as the on-screen EPG in mythtv. With this data, you can schedule recordings of individual programmes or entire series.
My problem seems to be the conversion of the channel names that my DVB-S knows about, compared to the differetn channel names listed in the Radio Times guide. Have to read up some more on that, but it seems to be easily overcome.
TV OUTMy video card is an XFX GeForce 6200A, which has VGA, S-Video, and DVI connectors. I got this card so I could use the S-Video output, and take the audio output via the optical SPDIF connector on the motherboard.
