[mythtv] PESPacket Fails CRC check everyday at 16:20

[scratch1701]

Hello,

Well, I got a gdb log of a crash which I *think* shows the closed
issue: #2664 (Backend SEGFAULT on invalid PMT)", crashing even on
r12750 on svn-trunk.

If anyone can confirm that this is correct, I'll post it to the ticket.
