Ok, I finally found a way to get clear QAM shows recorded as WTV files on my Fiji-patched systems converted to standard MPEG-TS with AC3 audio. Here's how!
1. Download GraphStudio (open source update of Microsoft's Graphedit)
2. Download Moonlight DumpOS and M71 MPEG Muxer directshow filters (just install the Moonlight stuff):
3. Run GraphStudio. Then open a WTV file on your Fiji machine. After a few seconds, it should come up with an algorithm for decoding and rendering the medial file. You can see WTV comes with a lot of baggage!
4. Now, highlight and delete the audio renderer (typically DirectSounds) and video renderer boxes. Then highlight and delete the audio and video decoders that the renderers used to be connected to. You should have two DTFilters left that used to be connected to the audio and video decoders. Leave everything else (unused baggage).
5. Now, using GraphStudio's menu insert two filters. First, the Moonlight M71 Muxer. Then, the Moonlight Dumpos (which should result in a window popping up asking you for the output filename. You can choose anything you want your output file to be called). Close the insert filter window.
6. Connect both the DTFilters to the input pin of the Muxer. Then connect the output of the Muxer to the input pin of the Dumpos.
7. Now, hit the "play" graph button! If everything works as it should, you should have a standard mpeg file at the end of the processing. Unfortunately for me, it looks as if processing occurred in realtime, meaning for a 2 hour WTV file, it took me 2 hours to get the MPEG-TS created.
Bummer about the processing time, but at least I can now have a standard MPEG-TS file that can be played on my other computers (WinXP, non-Fiji Vista, etc). **NOTE: You can get this MPEG-TS to be played back on other machines by installing a splitter. I used the Haali Media Splitter on my non-Fiji Vista system and was able to playback the TS file from within Vista Media Center via the Video Library.
Good luck!
