PDVD or TMT?

[banyaker]

Hi ,can you help me decide? I am curently using PDVD 7.3 Ultra for BD playback with many ongoing problems,Bd's that play one time then not the next,BD's that wont play at all etc etc etc.....
So me thinks its time to upgrade ,the choices being a bit limited do I fork out yet more hard earned cash on PDVD9 and probably invest in a heap more problems or do i purchase Arcsoft's 'Total Media Theatre'?
I believe they dont play this silly game of releasing a brand new version before the last one even works correctly and isnt quit as buggy,any experiences?
Will TMT playback non AACS discs as PDVD7 doesnt seem to?
Does TMT decode all the latest HD sound formats? (as i am using a 'Creative SB elite pro 'sound card which only had DD and DTS decoding)
Is the PQ/SQ as good as PDVD(when it works)?
Any input on this subject would be appreciated just need to know where to point my money.
Can i still have PDVD installed at the same time as TMT without problems?
I am still using XP Pro
