[mythtv-users] Error opening jump program file buffer ERROR

Hi all,

Mike in another email asked me to send my issue to this mailing list. 
I'm not a regular to send posts like that and hope I'm doing it well. In 
any case, receive my apologies.

Well, I saw that several people have the same error message: "Error 
opening jump program file buffer" when I change channels in live TV. 
When I choose the "See live TV" from the main menu, I see perfectly the 
starting channel. But when I try to change to another one, I have this 
message and I return to the main menu. I spent a lot of hours trying to 
find a solution or to bypass this problem. I saw that switching to 
another tuner card can resolve this issue. Unfortunately, I have only 
one tuner card. So, the fact is that I can see only 1 live channel with 
MythTV. I will really appreciate any help or tips or other feedbacks and 
I'm ready to give you any information that could help me and other users 
in the same position to enjoy MythTV at 100%. Thank you.

    I'm on Fedora 14: 2.6.35.13-91.fc14.x86_64
    My MythTV version (installed from yum): 0.24.1-2.fc14.x86_64
    The 3 previous versions have the same problem (in fact, I never
    reach to change channels)
    There are analogical channels, in NTSC, in Peru (Cable Magico)
    My TV tuner card: KWorld PCI Analog TV Card - PVR-TV 7134SE
    lspci command results: Philips Semiconductors SAA7134/SAA7135HL
    Video Broadcast Decoder based
    All the partitions in EXT4
    Seeing TV and changing channels works perfectly with other programs
    At the end, the log

    Installed programs:

        * mysql-server-5.1.56-1.fc14.x86_64
        * alsa-firmware-1.0.24.1-1.fc14.noarch
