I'm searching for a 1Hz to 100Hz frequency meter based on pic16F877 or pic16F84 for measuring Mains Frequency. I've already searched for the same but ended with 50Mhz frequency which gives error when measuring lower frequencies of 1 to 100 Hz.
Any advice/links will be appreciated.

Okay, okay, people have been so negative as to the idea of a pic playing MP3 files (even just 8kbps) so I have thought of an idea. How about a pic playing WAV files? When I get my pic interfaced to a HDD, then I'll be able to play WAV files. I won't have a file system, but instead lists of bytes with data.
So, any idea as to how to play (...)

I am not sure yet, but it seems that BCF and BSF instructions on pic 18F series behave very odd when a PORT is set to input mode. For example, if you do this:
BCF PORTB, 0
BSF PORTB, 1
then it seems there is no effect when using those instructions. However, if you do this:
