The dialog i get refers to max buffering exceeded. I can't exit from it and sometimes it just crashes there. With 0.25 and 0.26 (Master Head), I tried a few more experiments: 1. LiveTV - Remote frontend, Tune to a TV Channel within a few mins, it aborts almost immediately with ""max buffering exceeded"". Frontend will crash and needs to be restarted. 2. Recording - Now schedule the same channel, same show and start the recording. No remote frontend are viewing the stream. Recording proceeds with no problems. 3. Recording/then streaming to remote frontend - This works also. I tell myth to record the show, then watch the recording immediately after starting. I am guessing I have to use this as the workaround until the LiveTV streaming is more robust. It sucks that I can't channel surf anymore, but now I can watch almostLiveTV again. I am really doubting that this is a signal issue. If it was a signal issue, #2 would behavior exactly like #1 and would be aborted also. Also a majority of my recordings are finishing without any issues. However, LiveTV would consistently fail and most of the time fail immediately within the first 5 mins. Also #3 works, so it can't be a signal issue. I will attach the full logs next. {{{ (gdb) bt #0 0xb77a9424 in __kernel_vsyscall () #1 0xb51f91ef in __GI_raise (sig=6) at ../nptl/sysdeps/unix/sysv/linux/raise.c:64 #2 0xb51fc835 in __GI_abort () at abort.c:91 #3 0xb52342fa in __libc_message (do_abort=2, fmt=0xb532c3bc ""*** glibc detected *** %s: %s: 0x%s ***\n"") at ../sysdeps/unix/sysv/linux/libc_fatal.c:201 #4 0xb523ee42 in malloc_printerr (action=, str=, ptr=0x95626f8) at malloc.c:5007 #5 0xb5240fbf in _int_malloc (av=0xb536c440, bytes=40) at malloc.c:3470 #6 0xb5242d3c in __GI___libc_malloc (bytes=40) at malloc.c:2924 #7 0xb54d313b in qMalloc(unsigned int) () from /usr/lib/i386-linux-gnu/libQtCore.so.4 #8 0xb552ebef in QString::realloc(int) () from /usr/lib/i386-linux-gnu/libQtCore.so.4 #9 0xb552f23d in QString::append(QString const&) () from /usr/lib/i386-linux-gnu/libQtCore.so.4 #10 0xb5534bfe in QString::section(QString const&, int, int, QFlags) const () from /usr/lib/i386-linux-gnu/libQtCore.so.4 #11 0xb6cda1d1 in section (aflags=..., aend=, astart=, asep=..., this=) at /usr/include/qt4/QtCore/qstring.h:782 #12 SSDP::ProcessData (this=0x90bb330, pSocket=0x90b2bd8) at ssdp.cpp:356 #13 0xb6cdadad in SSDP::run (this=0x90bb330) at ssdp.cpp:301 #14 0xb6b09932 in MThreadInternal::run (this=0x91224e0) at mthread.cpp:79 #15 0xb54dade0 in ??
