Tinny audio when played on TV

I tried searching for this but didn't find anything.

When I burn a DVD in UVS 7 it plays back fine on my PC, but when I play it in the DVD player on our TV the audio is very tinny sounding through the TV speakers. Almost like it was recorded on a really poor microphone or played really loud on cheap PC speakers. It's the same through my stereo if I route the audio out on the TV through the stereo.

When I play the DVD on my PC the audio is fine. If I set my DVD player to output digital audio as PCM and route it straight to the stereo via digital coax it sounds perfect.

I'm capturing the video in a Sony DCRHC30 with 16 bit audio. I transfer the video to UVS with DV-AVI. I then convert the AVI to MPEG using MPEG audio before burning with the same MPEG properties.

The resulting MPEG has these properties:

Video Attributes:
Video compression mode: MPEG-2
TV system: 525/60 (NTSC)
Aspect Ratio: 16:9
Display Mode: Both Pan&scan and Letterbox
Source picture resolution: 720x480 (525/60)
Frame Rate: 29.97
Source picture letterboxed: Not letterboxed
Bitrate: 8.28Mbps

Audio Attributes:
Audio Coding mode: MPEG Audio Layer 2 Files
Sampling Rate: 48kHz, 16 Bit, Stereo
Audio application mode: Not specified
Number of Audio channels: 2
Bitrate: 224 Kbps
Number of Audio streams: 1

So my guess is that it has something to do with using MPEG audio, although I haven't tried using PCM when burning a DVD yet. It could also be my TV, though, if it's somehow messing up the audio when it arrives at the TV. Has anyone else had this problem?

Any thoughts?

Thanks
Kevin

Try applying the normalize filter to the audio.

I have UVS 7 SE, so I have almost no filters. I tried downloading the effects engine but it doesn't appear to work with 7 SE.

Kevin,
Your sound definitely should not be tinny. If it is OK on the PC and tinny on the DVD player, I would suspect the DVD player has a compatibility problem. Usually you can set the audio in the player for different encodings. Try them all.

If none work properly, you could change your audio to LCPM and re-render your video file. Then create a new DVD - this time using R/W media, just in case it does not work.
