First, It seems that PD8 is one of the better editing programs out there. I have tried a bunch of em, and they all have their issues. However, here are the issues I have found during my use of PD8.

(System is an Asus E8600/X38 8Gb, nvidia 8800GT, Hauppauge 1600, Win7-64-- with all the latest bios/drivers I can find; PD8 2220)

Processing .wtv files -- Powerdirector re-renders (and changes resolution of) these files when importing. The workaround is to first convert to dvrms format using Win 7. ( I know this issue has already been posted - thanks to the other folks out there!)

When converting dvrms files, audio sync gradually goes off by about a second per hour of recorded video for 720p content. The gradual sync offset does not occur when converting 480 or 1080i content. The workaround is to split the audio and experiment with shortening the audio clip duration until the sound is back in sync, then save that modified clip. Note, for short clips of a few minutes, this gradually increasing offset would not be noticed. When these same 720p dvrms files are played in WMC, the sync issue does not occur.

Sometimes when importing ts files from the Hauppauge capture program WinTV7, multiple copies appear in the PD media file list (like a dozen or so from the one file import action), and some files are listed as some hundreds of hours long, even though the clip is an hour or so. This makes any editing action difficult.

PD8 sometimes 'hangs' when doing dvrms conversion (not a crash). Processing starts quickly, then slows and grinds to a halt (I can tell by watching the file size progress in a windows explorer window). It happens on occasion, but I can't tell if it's a PD8 or a MS problem. Clicking cancel returns PD8 to normal operation

When converting 4:3 content broadcast in 16:9 format back to 4:3: The 16:9 file is imported to a 4:3 project and using aspect ratio control, choose crop to fill the screen. But saving as the default HQ dvd format results in severe jaggies. (It looks like 320x240 or worse). The workaround is to save as custom 480 progressive format, which results in a very nice looking 4:3 video.

Hauppauge 1600 - PD8 capture worked with an older hauppauge driver (2xxxx), but does not work with the current driver (2714.

My thanks to all in this forum, and hopefully this info is helpful.
