[mythtv-users] Live TV Playback is too slow - mythtv-0.21-211

[Jan Andrejkovic]

Hello guys,

I installed mythtv-0.21 from atrpms on Fedora 11 and I have DVB-T card WinTV
Nova-T USB2 and motherboard Jetway J7F2WE2G (CPU is VIA C7 2Ghz). I try to
run both backend and front end on the same box.

My problem is when I try to watch live tv, the picture is not smooth, it is
looks like slow motion. However when I tried to watch it in Kaffeine it was
OK. Also when watchiing Mythtv, CPU is loaded at about 50% so I believe it
has some spare power. I tried to renice frontend and backend but I did not
get any improvement.

Did anybody experience similar problem with mythtv?

Also my chipset is supposed to support mpeg-2 decompression - does anybody
know how can I check hardware decompression is used when playing TV? (I know
my WinTV card does not support hardware compression so this has to be done
by CPU).

My Device section in xorg.conf looks like:

Section "Device"
        Option      "AccelMethod"   "EXA"
        Option      "EnableAGPDMA" "true"
        Option      "ExaScratchSize"        "8192"
        Option      "MaxDRIMem"             "16384"
        Option      "MigrationHeuristic"    "greedy"
        Option      "ExaNoComposite" "True"

        Option      "VideoOverlay" "on"
        #Option     "VBEModes" "true"                     #This is causing
X11 to crash so I cannot enable it
        Identifier  "Card0"
        Driver      "openchrome"
        VendorName  "Unknown Vendor"
        BoardName   "Unknown Board"
        BusID       "PCI:1:0:0"
EndSection

Thank you very much in advance,

Jan
