WTV conversion in PD8 and 9 is one of the good features. However, there are several cautions:
Every channel has its own bit rate and resolution, and the bit rate can change from program to program - PD8 and 9 both react differently to these changes.
For instance, 720p seems to be the most 'difficult'. I find that after the conversion, the audio gradually goes off sync by about 37 frames per hour of program for both PD8 and 9. The workaround is to split the audio and shorten the audio track by 37 frames per hour.
PD8 does well when sourced by some of the 720p channels in the area, but is very sluggish editing 720 files broadcast by another channel.
PD9 also reacts very differently to different channel sources and recorded resolutions - that is why some folks have such troubles and some report very smooth operation.
There are some WTV to MPG conversion programs on the market if you look, but some (the one I have) down-converts surround audio to stereo. However, I find that PDx works the best with the files converted by the 3rd party program, but it is frustrating to lose surround sound.
PD9, at least on my rig, seems to be 'bit rate limited' during the wtv conversion and I see severe pixelation that occurs for about 5-20 frames after a significant scene change. That pixelation gradualy fades after the 5-20 frames. PD8 conversion of wtv files has no such pixelation. This does not occur each and every time, but often, and it is very annoying. This happens whether using the WTV file, or one converted by W7 to DVRMS format.
PD9 also has visible 'pulsing' of the overall brightnes level after rendering, It looks like the brighness gradually fades and returns in a 5-8 frame cycle every second or so. This is most visible on 720p sources. PD8 shows no sign of such brightness pulsing. Again, this is independent of whether the input file is WTV or DVRMS.
Both PD8 and PD9 result in some visible judder when the scene smoothly pans. I see this on 1080 as well as 720, but it is more visible on 720p sources. Other editing programs I have tried show no such judder after edit and render, using the identical input file.
As you can tell, I have been back and forth with PD8 and 9, having purchased both. I am still using PD8 awaiting (hopefully) a new patch for PD9.
I have done repeated PDx re-installs, up to the minute video driver updates, and repeated totally clean OS re-installs. The results are very consistent.
Hopefully this helps. I do suggest, if you want to use PD9, to find and get a 3rd party wtv to mpg converter. This will help some, but not all, of the problems with PD8/9 and WTV sources. Perhaps you can find one that preserves the surround format as well.
For information, the output format us usually mpg with at least the bit rate of the recorded channel with the same resolution of the source video - usually 12 to 20Mb/s or the default bit rate setting. I have also tried AVCHD output, using the same resolution as the source and either default or custom bit rates in the 10-20Mb/s range.
