@ Popcornmix Your a genius man. Your recommendations worked! At least for the audio and video glitching issue. Here is what i did:

I enabled "Turbo" overclocking settings manually in config.txt

arm_freq=1000
core_freq=500
sdram_freq=500
over_voltage=6

Starting from scratch again and all default settings except deinterlacing enabled. I still got the audio dropouts and video blinking. I do notice speed improvements here. In the past I have had issues with lockups at these overclock settings. I am even using heatsinks in my Pi. I will keep them for now and see if I still get lockups (I was using Raspmc and Xbian before which seems to be more temperamental with high overclocking)

I then enabled the following settings:

"Sync Playback To Display" enabled
"Adjust Display Refresh Rate to Match Video" Set to "On Start/Stop"
"Pause During Refresh Rate Change" set to 5 sec
I had "A/V Sync Method" set to "Video Clock (Resample Audio)
HW Acceleration was enabled
Audio output was set to 5.1 and passthrough enabled on Dolby Digital and DTS only
Vsync is "always enabled"
1080P resolution and 60Hz refresh rate for the GUI

With these settings I still got the audio drop outs and video blinking.

Now I tried setting gpu_mem to 352 (btw I did experience lockup and reboot a few times while navigating the gui with this setting so I suspect this was the cause)

With the higher gpu_mem I still got the audio drop outs and video blinking.

Next I set gpu_mem back to 256 and then tried your setting of hvs_priority=0x32ff

Now there are no audio random dropouts and video blinking.

If I comment out the hvs_priority setting the audio dropouts and video blinking returns. I tried this more than once to make sure it wasn't a coincidence.

The DVDPlayer issue was never resolved with any of these settings though. I always get no video and only audio when trying to playback the file with deinterlacing enabled. The only way I can get video and audio with deinterlacing is if I disable Openmax and keep hardware acceleration enabled (but this is bad because it is so slow it is unwatchable). I have tried disabling hardware accleleration completely and using software and I still get no video only audio with DVDPlayer and deinterlacing enabled.

Update: I think there is something with the .ts file that is causing the audio glitches at commercial changeovers (the onces that made me briefly lose audio sync). BUT I they only occur when I have my settings at default. It seems setting the following settings alleviates the glitches that occur at some commercial changeovers and once the main show starts.

"Sync Playback To Display" enabled
"Adjust Display Refresh Rate to Match Video" Set to "On Start/Stop"
"Pause During Refresh Rate Change" set to 5 sec
I had "A/V Sync Method" set to "Video Clock (Resample Audio)
HW Acceleration was enabled
Audio output was set to 5.1 and passthrough enabled on Dolby Digital and DTS only
Vsync is "always enabled"
1080P resolution and 60Hz refresh rate for the GUI

If i disable these settings and go back to default there are glitches on some commercial changes and at the start of the main show. This is most likely due to changes in the audio track in the recorded raw mpeg-2 .ts file (I can hear an obvious change in volume when it occurs). It's not big deal since that is expected. Sometimes when there is a change from stereo to surround the files don't play at all. I don't believe this is the fault of the Pi though. Raw .ts files don't always work well on media players because it's just dumping a raw mpeg-2 stream into a file. I'm not sure if my uploaded .ts file will exhibit this because I used VideoRedo to cut the sample. Sometimes VideoRedo fixes these types of issues in audio tracks.
