Long time mythtv/mythbuntu user. I rebuilt my BE/FE system because it was low powered (AMD Athlon XP, GeForce 6200, 2 GB RAM, and analog tuners only). Because my tv provider (Comcast) stopped broadcasting analog signal, we could no longer record tv.
The new BE/FE system was built to for recording digital tv, capturing vhs movies, storing/playing videos, and storing/playing music.

What Works Flawlessly:
All hardware worked out of the box. I am using the pcHDTV to record digital (DBS) broadcasts only, while the PVR 500 is connected to a VCR to record VHS videos. The system has plenty of power to play high definition videos smoothly.
Initially the pcHDTV card was unable to pick up all of the tv channels and there was some pixelation with recordings. The fault was not the pcHDTV card, but rather a weak signal (<80%) due to splitting the coaxial cable between MythTV and the TV. I also had the other splits left over from the previous BE/FE system. Removing all of the coaxial cable splitters (1-three way and 1-two way) and a single coaxial cable from the wall to the pcHDTV increased the signal to >90%. The pcHDTV was then able to pick up all of the tv channels and pixelation in the recordings was eliminated.
What's Not Resolved:
Screen resolution 1280x720 does not fit in the tv screen (top task bar cannot be seen except for a few pixels). I have been unable to adjust the screen to fit the tv using tv zoom feature or MythTV utilities. This is more annoying than a significant problem. The fact that xfce allows right-clicking on the desktop for access to programs is really appreciated.
Mythweather doesn't work very well for me. Current conditions works, but none of the other screens in Mythweather even though the source is configured.
Other than the above, Mythbuntu software works very well.
Thank you Mythbuntu team and MythTV developers.
