[mythtv] crash when livetvbuffer full

[Steven]

Just noticed these on a system with livebuffer set to 1GB. When the 
buffer is full back- and frondend crash.

In mythbackend log :

ERROR: file I/O problem in 'safe_read()': Invalid argument

In mythfrontendlog :

2005-02-14 15:55:53.126 RemoteFile::Read() failed in 
RingBuffer::safe_read().
2005-02-14 15:55:53.194 prebuffering pause

Happens in CVS from last week and still happens after CVS recompile today.
