[mythtvnz] VDPAU package can be removed?

[Dylan Hall]

I have the same TV and I don't use any mode lines to drive it, I just
let the driver figure it out for itself. The only caveat is that the TV
needs to be switched on and connected if you reboot so that the video
card can probe the TV when X starts.

I've extracted the edid data with "get-edid" and attached the results.

Running that through "parse-edid" it generates the following:

parse-edid: parse-edid version 1.4.2
parse-edid: EDID checksum passed.

        # EDID version 1 revision 3
Section "Monitor"
        # Block type: 2:0 3:fc
        Identifier "SONY TV"
        VendorName "SNY"
        ModelName "SONY TV"
        # Block type: 2:0 3:fc
        # Block type: 2:0 3:fd
        HorizSync 14-68
        VertRefresh 48-62

        Mode    "1360x768"      # vfreq 60.015Hz, hfreq 47.712kHz
                DotClock        85.500000
                HTimings        1360 1424 1536 1792
                VTimings        768 771 777 795
                Flags   "+HSync" "+VSync"
        EndMode
        Mode    "1280x720"      # vfreq 60.000Hz, hfreq 45.000kHz
                DotClock        74.250000
                HTimings        1280 1390 1430 1650
                VTimings        720 725 730 750
                Flags   "-HSync" "-VSync"
        EndMode
        # Block type: 2:0 3:fc
        # Block type: 2:0 3:fd
EndSection


I assume the 1360x768 at 60 mode above is the one the driver figures out
for itself. It doesn't look like the panel is reporting a 50Hz mode.

I'm curious, why do you need/want 50Hz?
